Impact of Influencing Factors on CO2 Emissions in the Yangtze River Delta during Urbanization
Authors: Xue Yixi , Ren Jie , Bi Xiaohang
Published: August 2019

The Yangtze River Delta (YRD) is China’s largest urban agglomeration with a rapid urbanization process. This paper analyzes the dynamic relationship between urbanization rate, energy intensity, GDP per capita, and population with CO2 emissions in YRD over 1990–2011 based on the extended STIRPAT model, impulse response function, and variance decomposition. A support vector machine model was constructed to further predict the scenarios of YRD’s CO2 emissions from 2015–2020. The results show that YRD’s CO2 emissions continuously increased during the sample period and are predicted to increase over 2015–2020. Energy intensity is the most influential factor, both in the short and long term, and the total population contributes the least. However, the influencing magnitude of energy intensity tends to decrease in the long term. The increase of urbanization rate is still accompanied by the increase of CO2 emissions in YRD, but an inverted-U shape relationship between them may exist in the long term. The contribution of GDP per capita to CO2 emissions is higher than the population and urbanization rate, and its contribution rate for CO2 emissions is growing. The Kuznets curve does not exist in the current YRD.
Innovations’ Success and Failure in the Business Cycle
Authors: Salas-Fumás Vicente , Ortiz Javier
Published: August 2019

This paper examines three channels of influence of the business cycle in the propensity of firms to introduce technological innovations: Aggregate demand (firms initiate more innovation projects in expansion than in recession; risk (the probability that initiated projects fail is higher in contraction than in expansion); and obstacles to innovate (more firms perceive the obstacles to innovate as high in recessions than in expansions and the high obstacles implies lower propensity to initiate innovation projects). With Spanish CIS data we find evidence that the three channels contributed to the fall in the proportion of firms that introduce technological innovations during the Great Recession, compared with the proportion of innovators in the years of expansion. The research methodology consists on estimating a multiprobit model with the probability that firms introduce technological innovations, the probability that firms abandon ongoing innovation projects, and the probability that firms perceive the obstacles to innovate as high.

Published: August 2019

One of the most important parameters in sustainable urban land valuation is the risk premium. Correct assessment of the risk premium is essential for sustainable valuation. Generally, it is estimated that traditional financial models or historic rates do not take into account the specific risk factors of an investment project. In this paper, we propose a sustainable model to obtain it. It is based on investment risk factors and the urban planning land development stages. We conducted a study in Badajoz, Spain, on four urban stages: first, land without an execution program; second, land with an execution program; third, land with reparceling; and fourth, fully developed and urbanized land. We calculated one different risk premium value for each urban stage. The results show that with this model, we can obtain the risk premium at any time during urban planning development. The urban stage is one of the most influential factors in the risk premium value. It decreases during urban planning development, and fully developed and urbanized land has a lower risk premium.
Is Smart Housing a Good Deal? An Answer Based on Monte Carlo Net Present Value Analysis
Authors: Elariane Sarah A. , Dubé Jean
Published: August 2019

The smart cities are considered to be an engine of economic and social growth. Most countries started to convert their existing cities into smart cities or construct new smart cities in order to improve the quality of life of their inhabitants. However, the problem that facing those countries while applying the concept of smart cities is the costs, especially for the residential sector. Despite the high initial and even operation costs for adopting different technologies in smart housing; the benefits could exceed those costs within the lifespan of the project. This article is shedding the light on the economics of smart housing. This study aims to evaluate the net present value (NPV) of a smart economic housing model to check the viability and feasibility of such projects. The calculation of the NPV based on Monte Carlo simulation provides an interesting methodological framework to evaluate the robustness of the results as well as providing a simple way to test for statistical significance of the results. This analysis helps to evaluate the potential profitability of smart housing solutions. The research ends up by proving the feasibility of this type of project.
A Novel Dissimilarity of Activity Biomarker and Functional Connectivity Analysis for the Epilepsy Diagnosis

Published: August 2019

Epilepsy is a central nervous system disorder that results in asymmetries of brain regional activation and connectivity patterns. The detection of these abnormalities is oftentimes challenging and requires identification of robust bio-markers that are representative of disease activity. Functional Magnetic Resonance Imaging (fMRI) is one of the several methods that can be used to detect such bio-markers. fMRI has a high spatial resolution which makes it a suitable candidate for designing computational methods for computer-aided biomarker discovery. In this paper, we present a computational framework for analyzing fMRI data consisting of 100 epileptic and 80 healthy patients, with an overall goal to produce a novel bio-marker that is predictive of epilepsy. The proposed method is primarily based on Dissimilarity of Activity (DoA) analysis. We demonstrate that the bio-marker presented in this study can be used to capture asymmetries in activities by detecting any abnormalities in Blood Oxygenated Level Dependent (BOLD) signal. In order to represent all asymmetries (of connectivity and activation patterns), we used functional connectivity analysis (FCA) in conjunction with DoA to find underlying connectivity patterns of the regions. Subsequently, these biomarkers were used to train a Support Vector Machine (SVM) classifier that was able to distinguish between healthy and epileptic patients with 87.8% accuracy. These results demonstrate the applicability of computer-aided methods in complex disease diagnosis by simply utilizing the existing data. With the advent of all modern sensing and imaging techniques, the use of intelligent algorithms and advanced computational methods are increasingly becoming the future of computer-aided diagnosis.
The Immobilization of ChEMBL474807 Molecules Using Different Classes of Nanostructures
Authors: Czeleń Przemysław , Szefler Beata
Published: August 2019

Indirubin derivatives and analogues are a large group of compounds which are widely and successfully used in treatment of many cancer diseases. In particular, the ChEMBL474807 molecule, which has confirmed inhibiting abilities against CDK2 and GSK3B enzymes, can be included in this group. The immobilization of inhibitors with the use of nanocarriers is an often used strategy in creation of targeted therapies. Evaluations were made of the possibility of immobilizing ligand molecules on different types of nanocarrier, such as carbon nanotubes (CNT), functionalized fullerene C60 derivatives (FF_X), and functionalized cube rhombellanes, via the use of docking methods. All results were compared with a reference system, namely C60 fullerene. The realized calculations allowed indication of a group of compounds that exhibited significant binding affinity relative to the ligand molecule. Obtained data shows that structural modifications, such as those related to the addition of functional groups or changes of structure symmetry, realized in particular types of considered nanostructures, can contribute to increases of their binding capabilities. The analysis of all obtained nano complexes clearly shows that the dominant role in stabilization of such systems is played by stacking and hydrophobic interactions. The realized research allowed identification of potential nanostructures that, together with the ChEMBL474807 molecule, enable the creation of targeted therapy.
CMB Tensions with Low-Redshift H0 and S8 Measurements: Impact of a Redshift-Dependent Type-Ia Supernovae Intrinsic Luminosity
Authors: Martinelli Matteo , Tutusaus Isaac
Published: August 2019

With the recent increase in precision of our cosmological datasets, measurements of Λ CDM model parameter provided by high- and low-redshift observations started to be in tension, i.e., the obtained values of such parameters were shown to be significantly different in a statistical sense. In this work we tackle the tension on the value of the Hubble parameter, H 0 , and the weighted amplitude of matter fluctuations, S 8 , obtained from local or low-redshift measurements and from cosmic microwave background (CMB) observations. We combine the main approaches previously used in the literature by extending the cosmological model and accounting for extra systematic uncertainties. With such analysis we aim at exploring non standard cosmological models, implying deviation from a cosmological constant driven acceleration of the Universe expansion, in the presence of additional uncertainties in measurements. In more detail, we reconstruct the Dark Energy equation of state as a function of redshift, while we study the impact of type-Ia supernovae (SNIa) redshift-dependent astrophysical systematic effects on these tensions. We consider a SNIa intrinsic luminosity dependence on redshift due to the star formation rate in its environment, or the metallicity of the progenitor. We find that the H 0 and S 8 tensions can be significantly alleviated, or even removed, if we account for varying Dark Energy for SNIa and CMB data. However, the tensions remain when we add baryon acoustic oscillations (BAO) data into the analysis, even after the addition of extra SNIa systematic uncertainties. This points towards the need of either new physics beyond late-time Dark Energy, or other unaccounted systematic effects (particulary in BAO measurements), to fully solve the present tensions.

Published: August 2019

The European standard on transport logistics and services in public passenger transport EN 13816 is based on a relationship between the perception of users and transport carriers throughout the groups of criteria taken as a basis for observation in this paper. The constant development and improvement of services in order to achieve sustainability of passenger transport is an imperative on the one hand and a challenge on the other. This is highly evident in persons with disabilities who are faced with many physical and social barriers related to access to rail transport. In this paper, a new model for the selection of criteria for the quality of passenger service in rail transport, from the perspective of persons with disabilities as the main category of passengers, has been created. The survey has covered 168 criteria classified in several groups and the entire territory of Serbia. In order to select the most important criteria, a new model that implies the integration of Full Consistency Method and a Rough Power Heronian aggregator has been developed. The development of a new aggregator enables more accurate decision-making in the process of group decision-making. The results obtained in this paper show that the most important criteria according to importance are Accessibility, Availability, Security, Time, Customer care, Information, Comfort, Environmental impact. Based on the criteria obtained for the service quality of rail transport for persons with disabilities, railway carriers will be able to change and improve the existing services, content, characteristics, equipment of railway stations and vehicles.

Published: August 2019

The short-term effects of botulinum toxin type A (BoNT-A) treatment in stroke patients with upper extremity are well established. This study examined the association between the recovery of motor function of the upper extremity with subjective physical symptoms in outpatients receiving long-term BoNT-A and occupational therapy following stroke. We also investigated the expectations of patients who elected to continue treatment. Forty-seven patients (23 men and 24 women) aged 61 years received BoNT-A treatment more than 20 times. The subjective physical status was analyzed by using the visual analogue scale score through an eight-item questionnaire. Recovery of motor function in the upper extremity was detected by calculating the change (delta) in Fugl–Mayer Assessment (FMA), and ordinal logistic modeling analysis was used to determine the association between the delta-FMA score and the subjective level of agreement for each item. When the ordinal logistic modeling fit was statistically significant, results were interpreted as having logistic probability. The logistic curves discriminating one point (strongly disagree) from five points (strongly agree) were fit in a stepwise fashion. This study suggests that patients receiving long-term BoNT-A treatment and occupational therapy experienced an increased upper extremity mitigation and decreased insomnia after injection, regardless of the recovery of motor function.

Fusarium mycotoxins (FUS) occur frequently in poultry diets, and regulatory limits are laid down in several countries. However, the limits were established for exposure to a single mycotoxin, whereas multiple contamination is more realistic, and different studies have demonstrated that it is not possible to predict interactions between mycotoxins. The purpose of this study was thus to compare the toxic effect of deoxynivalenol (DON), fumonisins (FB) and zearalenone (ZON), alone and in combination on broiler chickens, at the maximum tolerated level established by the EU for poultry feed. Experimental corn-soybean diets incorporated ground cultured toxigenic Fusarium strains. One feed was formulated for chickens 0 to 10 days old and another for chickens 11 to 35 days old. The control diets were mycotoxin free, the DON diets contained 5 mg DON/kg, the FB diet contained 20 mg FB1 + FB2/kg, and the ZON diet contained 0.5 mg ZON/kg. The DONFBZON diet contained 5, 20, and 0.5 mg/kg of DON, FB1 + FB2, and ZON, respectively. Diets were distributed ad libitum to 70 broilers (male Ross PM3) separated into five groups of 14 chickens each reared in individual cages from one to 35 days of age. On day 35, after a starvation period of 8 h, a blood sample was collected, and all the animals were killed and autopsied. No difference between groups that could be attributed to FUS was observed in performances, the relative weight of organs, biochemistry, histopathology, intestinal morphometry, variables of oxidative damage, and markers of testicle toxicity. A significant increase in sphinganine and in the sphinganine to sphingosine ratio was observed in broilers fed FB. Taken together, these results suggest that the regulatory guidelines established for single contamination of broiler chickens fed with DON, FB, and ZON can also be used in the case of multiple contamination with these toxins.

Published: August 2019

Capybaras (Hydrochoerus hydrochaeris), the world’s largest rodents, are distributed throughout South America. These wild herbivores are commonly found near water bodies and are well adapted to rural and urban areas. There is limited information on the viruses circulating through capybaras. This study aimed to expand the knowledge on the viral diversity associated with capybaras by sampling their faeces. Using a viral metagenomics approach, we identified diverse single-stranded DNA viruses in the capybara faeces sampled in the Distrito Federal, Brazil. A total of 148 complete genomes of viruses in the Microviridae family were identified. In addition, 14 genomoviruses (family Genomoviridae), a novel cyclovirus (family Circoviridae), and a smacovirus (family Smacoviridae) were identified. Also, 37 diverse viruses that cannot be assigned to known families and more broadly referred to as unclassified circular replication associated protein encoding single-stranded (CRESS) DNA viruses were identified. This study provides a snapshot of the viral diversity associated with capybaras that may be infectious to these animals or associated with their microbiota or diet.

As one of the most destructive and costly natural disasters, drought has far-reaching negative effects on agriculture, water resources, the environment, and human life. Scientific understanding of propagation from meteorological to hydrological drought is of great significance for accurate forecasting of hydrological drought and preventing and mitigating drought disasters. The objective of this study is to analyze the spatio-temporal variational characteristics of propagation from meteorological drought to hydrological drought and the associated driving mechanisms in the eastern Qilian Mountains using the standard precipitation index (SPI), standardized runoff index (SRI), and drought propagation intensity index (DPI). The results show that there has been meteorological humidification and hydrological aridification in the upper reaches of the Shiyang River Basin over the last 56 years; especially in the 2000s, the intensity of hydrological drought was the strongest and the intensity of meteorological drought was the weakest, indicating the propagation intensity of meteorological drought to hydrological drought was extremely strong during this period. The changes of meteorological and hydrological dry–wet are different, both on seasonal and monthly scales. The meteorological dry–wet is shown to have had a significant effect both on the current and month-ahead hydrological dry–wet, where the one-month lag effect was most obvious. The relationship between meteorological and hydrological droughts also vary in space: Hydrological aridification in the Huangyang River, and the rivers east of it, was greater than that in the western tributaries. The drought propagation intensities from west to east showed a decreasing trend, excluding the Huangyang River. Climate and land-use changes are the main factors affecting the propagation from meteorological drought to hydrological drought. When the natural vegetation area accounted for between 76.3–78%, the cultivated land area between 0.55–3.6% and the construction area between 0.08–0.22% were a peer-to-peer propagation process from meteorological drought to hydrological drought in the upper reaches of the Shiyang River.
Hydrologic Response in an Urban Watershed as Affected by Climate and Land-Use Change
Authors: Aboelnour Mohamed , Gitau Margaret W. , Engel Bernard A.
Published: August 2019

The change in both streamflow and baseflow in urban catchments has received significant attention in recent decades as a result of their drastic variability. In this research, effects of climate variation and dynamics of land use are measured separately and in combination with streamflow and baseflow in the Little Eagle Creek (LEC) watershed (Indianapolis, Indiana). These effects are examined using land-use maps, statistical tests, and hydrological modeling. Transition matrix analysis was used to investigate the change in land use between 1992 and 2011. Temporal trends and changes in meteorological data were evaluated from 1980–2017 using the Mann–Kendall test. Changes in streamflow and baseflow were assessed using the Soil and Water Assessment Tool (SWAT) hydrological model using multiple scenarios that varied in land use and climate change. Evaluation of the model outputs showed streamflow and baseflow in LEC are well represented using SWAT. During 1992–2011, roughly 30% of the watershed experienced change, typically cultivated agricultural areas became urbanized. Baseflow is significantly affected by the observed urbanization; however, the combination of land and climate variability has a larger effect on the baseflow in LEC. Generally, the variability in the baseflow and streamflow appears to be heavily driven by the response to climate change in comparison to variability due to altered land use. The results reported herein expand the current understanding of variation in hydrological components, and provide useful information for management planning regarding water resources, as well as water and soil conservation in urban watersheds in Indiana and beyond.
First Steps into an Integrated Karst Aquifer Vulnerability Approach (IKAV). Intrinsic Groundwater Vulnerability Analysis of the Yucatan Karst, Mexico

Published: August 2019

Karst groundwater vulnerability maps are important tools for the development of groundwater management and protection strategies. However, current methodologies do not always match regional characteristics and parameter adaptations are necessary. In addition, other important processes such as dilution and aquifer residence time are not included in vulnerability analysis for the complications of evaluating two or more criteria simultaneously. The integrated karst aquifer vulnerability approach (IKAV) project aims to develop an integrated approach to include these parameters and estimate global change implications in current and future scenarios. As a first step, intrinsic vulnerability methodologies are studied in order to highlight important parameters and the congruence with regional characteristics of the Yucatan karst. Results demonstrate agreement between methods for the evaluation of high and very high vulnerabilities and their relation with fissures and dolines. Moderate vulnerabilities are assigned to more than 50% of the area. However, moderate vulnerabilities, assigned to the coastal area and the Southern hill, are highly questionable. Intrinsic features affecting moderate classes vary according to the method. Parameter sensitivity analysis and overlap analysis demonstrate the influence of depth to the unsaturated zone, soils, precipitation, and slope on moderate values. Therefore, such parameters must be re-evaluated and discretized according to the characteristics of the study area to match Yucatan regional characteristics.

New Analytic Solutions for Galaxy Evolution: Gas, Stars, Metals, and Dust in Local ETGs and Their High-z Star-forming Progenitors

Published: August 2019

We present a set of new analytic solutions aimed at self-consistently describing the spatially averaged time evolution of the gas, stellar, metal, and dust content in an individual star-forming galaxy hosted within a dark halo of a given mass and formation redshift. Then, as an application, we show that our solutions, when coupled to specific prescriptions for parameter setting (inspired by in situ galaxy–black hole coevolution scenarios) and merger rates (based on numerical simulations), can be exploited to reproduce the main statistical relationships followed by early-type galaxies and their high-redshift star-forming progenitors. Our analytic solutions allow one to easily disentangle the diverse role of the main physical processes regulating galaxy formation, quickly explore the related parameter space, and make transparent predictions on spatially averaged quantities. As such, our analytic solutions may provide a basis for improving the (subgrid) physical recipes presently implemented in theoretical approaches and numerical simulations and can offer a benchmark for interpreting and forecasting current and future broadband observations of high-redshift star-forming galaxies.

Cette nouvelle catégorie permet de mesurer le chômage et grâce à de nouvelles mesures législatives, de placer les chômeurs, de les assurer et d’organiser le marché du travail. Elle est l’œuvre des réformateurs sociaux répartis notamment au sein de plusieurs Associations internationales privées de politique sociale. Édouard Fuster en fait partie à des titres divers. Il participe à la création de l’Association internationale de lutte contre le chômage en 1910 et s’y prononce en faveur de l’assurance obligatoire contre le chômage. Si la guerre met fin à l’activité de ces associations, leurs membres les plus actifs agissent dans leurs spécialités aux niveaux nationaux. L’Organisation internationale du travail créée en 1919 s’empare du problème du chômage au niveau international : normes législatives destinées à uniformiser statistiques, placement et assurance ; enquêtes destinées à comprendre et résoudre le chômage né des crises de 1921-1922 et de 1929. Enfin, l’OIT contribue à la fusion des associations de politique sociale d’avant-guerre sur lesquelles elle compte s’appuyer, et pour laquelle Fuster joue un rôle important comme expert.
Une approche morale de la précarité. Les enquêtes des services sociaux dans l’entre-deux-guerres
Authors: Zappi Lola
Published: August 2019

Alors que le service social naît dans l’entre-deux-guerres en se pensant comme un outil nouveau de résolution de la « question sociale », comment les services sociaux de l’époque appréhendent-ils la précarité économique des familles populaires sous leur charge ? Pour répondre à cette question, l’article propose de se tourner vers l’outil privilégié de ces organismes : l’enquête, menée auprès de toute famille éligible à une aide sociale. La construction même de l’enquête, à travers ses différentes étapes (visite à la famille, visite de voisinage), comme dans sa mise en forme écrite (notamment par la reconstitution des budgets ouvriers) est en effet pensée par les assistantes sociales sous un angle moral, celui consistant à débusquer les « mauvais pauvres ». Bien que les enquêtes mettent au jour le profil de familles populaires touchées par une précarité économique structurelle, les services sociaux adoptent une approche morale tendant à rendre les personnes enquêtées responsables de leur situation, accusant leur mauvaise gestion budgétaire et leurs consommations coupables. Les enquêtes sont ainsi utilisées par les services sociaux dans une visée de moralisation des pratiques populaires et non en faveur d’un projet de protection sociale.
Tenir son budget en temps de crise. Enquête auprès d’un couple espagnol après la récession de 2008
Authors: Blavier Pierre
Published: August 2019

La Grande Récession de 2008 en Espagne constitue un cas exemplaire de changement économique soudain et de grande ampleur, marqué par une très forte augmentation du chômage et un déclin de la consommation. De telles évolutions sont souvent appréhendées des points de vue d’institutions publiques ou macroéconomiques. Cet article propose de faire un pas de côté par rapport à ces approches, à partir de l’étude monographique d’un ménage de classe moyenne, composé d’un couple et de deux enfants d’une dizaine d’années, dans la région de Valencia. Ceci permet de documenter les « tensions budgétaires » qu’a occasionnées la crise et les ajustements pratiques utilisés pour y répondre : la consommation du ménage doit être comprise en lien avec des enjeux tels que l’éducation des enfants, la recherche d’emploi de la mère de famille, ou les modifications de l’emploi d’indépendant du mari. L’enquête permet ainsi de cerner ce qui constitue le « travail de consommation », c’est-à-dire la manière dont divers domaines et évaluations sont à prendre en compte pour comprendre comment fonctionne l’économie domestique, de manière générale et en temps de crise en particulier.
« Nous sommes aux bords d’un univers statistique quasiment inconnu » : le Crédoc et la quantification de la consommation (France, années 1950)
Authors: Boulat Régis
Published: August 2019

Grâce aux experts du Commissariat du Plan et au Fonds national de la productivité, le Centre de recherche et de documentation sur la consommation (Crédoc) voit le jour en 1953 afin de pallier les retards français en matière de quantification de la consommation. Alors qu’il s’agit de reconstruire la France tout en la modernisant, les enquêtes du Crédoc basées sur des méthodes innovantes vont permettre aux technocrates et aux patrons de mieux connaitre les comportements des ménages français et de comprendre les logiques d’une société de consommation en plein essor.
L’intelligence artificielle des marchés : comment les systèmes de recommandation modélisent et mobilisent les consommateurs
Authors: Vayre Jean-Sébastien , Cochoy Franck
Published: August 2019

Cet article aborde un type particulier d’outils d’automatisation des enquêtes sur les consommateurs : les systèmes ou agents de recommandation. L’étude de ce cas particulier permet de mieux comprendre comment ont pu évoluer, au cours du temps, d’une part les systèmes d’automatisation des enquêtes sur les consommateurs et, d’autre part, les enjeux contemporains qui sont liés au déploiement des innovations réalisées dans ce domaine. L’article montre d’abord que l’automatisation actuelle des enquêtes sur les consommateurs se fonde sur l’avènement d’un nouveau régime cognitif qui repose sur la captation et l’exploitation de l’attention des consommateurs. Il présente ensuite les techniques d’intelligence artificielle mises en œuvre pour mobiliser les consommateurs. Il examine enfin les problèmes que soulèvent ces technologies, mais aussi quelques pistes susceptibles d’aider à les surmonter.

The equivalent circuit imitating wave scattering by arrays of split-ring resonators

Published: August 2019

The scattering of waves by a periodic chain of series resonant LC circuits in a two-dimensional lattice of lumped elements is considered, that imitates the scattering of electromagnetic waves by a periodic lattice of split-ring resonators. Using the translation symmetry of this chain we transformed the scattering problem into the problem of wave propagation along the strip with a single LC circuit. This problem was solved analytically presenting the transmittance as a sum of partial transmittances, corresponding to the frequency mini-bands of the strip. It is shown that the transmittance as a function of the incident wave frequency demonstrates two types of resonances with different resonant frequency dependence on the distance between neighbouring LC circuits.
An
N‐person war of attrition with the possibility of a noncompromising type
Authors: Kambe Shinsuke
Published: August 2019

This paper studies an
N‐person war of attrition that needs one exit for its ending. An
N‐person war of attrition is qualitatively different from its two‐person version. Only in the former, may the set of players who are actively engaged in a war of attrition change over time. We introduce the possibility of a noncompromising type and characterize the unique equilibrium by identifying which players are actively involved in a war of attrition at each moment. We examine who is likely to exit and when the war of attrition ends quickly. As the leading example, we study how a group selects a volunteer in a dynamic setting.

Published: August 2019

In this paper, the properties of the base metal of the low-alloy high-strength steel 20MnTiB, the welding process and the microstructure and properties of the welded joints were studied. The results are as follows: post-heat treatment below 400°C, the strength change of the steel decreases slowly, the elongation does not change significantly, and the metallographic structure is not obvious. When the temperature is above 400, the strength is greatly reduced. And its plasticity increases remarkably, and precipitates on the grain boundary are precipitated and grown on the metallographic structure. When the line energy is in the range of 9.6~12.0kJ/cm, the mechanical properties and microstructure of the welded joints meet the requirements, and the welding process that meets the requirements is studied. Finally, the mechanical properties and microstructure of the welded joint are studied. Provide a reference for the research and application of steel.
