Authors: Yao Sisi 
Published: June 2020

Abstract
As an important means to effectively optimize land use, land remediation projects need to be systematically analyzed for their qualitative and quantitative impacts on soil carbon retention. In this study, three types of land remediation project areas, namely sandy land, saline-alkali land, and abandoned residential land in Shaanxi Province, were selected as research objects, and the impact of land remediation years on soil carbon retention capacity was analyzed. The results of this study indicate that due to differences in basic soil properties and engineering implementation technologies, different types of land remediation have different effects on soil carbon retention characteristics. Aeolian sandy land, abandoned homesteads, and saline-alkali land remediation have certain effects on soil carbon retention.

Authors: Liu Weihua , Tian Baohui 
Published: June 2020

Abstract
In order to address the skin effect in 3-D density imaging, a sampling weighting function was introduced, which is similar to the distribution of kernel function. It can describe the attenuation of density cell with depth, and also can describe the attenuation of density cell in horizontal distance. Taking the sampling weighting function as the constraint condition, the single abnormal body model was inversion. Compared with the case without weighting function constraint, the inversion results are in better agreement with the model data. The results show that the sampling weighting function is potential as a constraint in 3D density imaging.

Authors: Lu Zhengyan 
Published: June 2020

Abstract
The continuous development of China’s economic level and the increasing improvement of people’s living standards have directly promoted the development of China’s construction industry. However, in the construction of buildings, people often ignore the problem of waste of resources. To a certain extent, it also caused a lot of waste. Therefore, I believe that it is necessary to construct a scientific view of building energy conservation and apply it to actual building construction. Therefore, this paper addresses the problems of unclear scientific understanding of building energy efficiency and weak theoretical basis of engineering practice, and puts forward the necessity of the construction of a scientific view of building energy conservation and its application research. From the concept of energy, the development of building science, the development of building disciplines, and the connection between science, engineering, technology and industry, it reveals the inherent connection of building energy conservation science, building energy conservation engineering, building energy conservation technology and building energy conservation industry. Aiming at the characteristics of building energy as a social activity, the practice activity is constructed from the perspectives of the subject, object, content, and goals to form a multi-angle and multi-level understanding system of building energy efficiency. Form an epistemological system for building energy efficiency.

The preparation methods of heterogeneous catalysts include precipitation method, impregnation method, precipitation impregnation method, sol-gel method and chemical deposition method. According to the different ways of adding metal solution and precipitant, the precipitation method is divided into positive addition method, reverse addition method and combined addition method. According to the impregnation amount, the impregnation method can be divided into equal amount and excessive impregnation method. According to the principle of chemical reaction engineering, heterogeneous CWAO reaction process can be divided into 7 processes, such as internal diffusion and external diffusion. CWAO method is expected to be applied and expanded in pesticide, printing and dyeing, papermaking and other industries.

Abstract
In the experiment, the COD removal rate of water samples was used as the evaluation index of catalyst activity, and the dissolution concentration of metal ions was used as the evaluation index of catalyst stability, and the activity and stability of the catalyst were comprehensively evaluated. The Pd-catalyst was used to treat simulated printing and dyeing waste-water by CWAO, and the influence of calcination temperature on the performance of the catalyst was investigated. The results showed that as the calcination temperature increases, the decolorization rate of the catalyst treatment waste-water decreases, and the metal stripping concentration of the waste-water decreases. The COD removal rate of the waste-water at the set 6 temperatures was 87.84 %, 85.43 %, 84.72 %, 77.59 %, 68.04 % and 66.94 %. The dissolved Cu and Fe concentrations of the waste-water at 90 minutes were 0.46 mg/L and 49.22 mg/L. Pd-catalyst has good catalytic activity and stability.

Authors: Liu Longjiang , Xiang Pengzhi , Huang Yao 
Published: June 2020

AbstractPolymethyl methacrylate (PMMA) was prepared by emulsion polymerization using methyl methacrylate (MMA) as monomer, potassium per sulfate as initiator. Polymethyl methacrylate/mesoporous molecular sieve composite (PMMA/MCM-48) was synthesized via the addition of mesoporous molecular sieve MCM-48 silica nanomaterial. The synthesized samples were systematically characterized using XRD, SEM, TEM, FT-IR, and TG. The results showed that PMMA microspheres with a diameter of 80-110 nm were prepared by emulsion polymerization. Compared with pure PMMA, PMMA/mesopores molecular sieve MCM-48 composites have good thermal stability. Pure PMMA microspheres can be completely decomposed at a lower temperature (400°C), and the thermal stability of PMMA/MCM-48 composites were improved by the addition of mesoporous molecular sieves.

Published: June 2020

Abstract
Semi-rigid base course is widely applied in pavement construction. However, because the inorganic binder tends to be affected easily by environmental factors (temperature, moisture), the cracking of semi-rigid base course is a serious problem, which causes reflection cracks on the surface layer. That is one of the main damage types of this kind of pavement structure. In view of the above problems, scholars all over the world have carried out researches on the cracking mechanism and the causes of cracks. Combined with engineering practices, various kinds of reflective crack prevention technologies have been proposed. In this paper, the author systematically investigates the existing retarding methods. According to their characteristics, it is mainly divided into three categories: surface anti-cracking treatment, base anti-cracking treatment and stress absorption structure addition. Meanwhile, the main principles and effects of these three categories of measures are analysed and summarized to provide the reference for subsequent study and design.

Authors: Zheng Jianjun , Tian Feng , Chen Hao , Shi Xianda , Yu Xiao 
Published: June 2020

Abstract
As common electrical equipment, composite insulator played an important role on the safe and stable operation of transmission lines. Hence, it was meaningful to explore effective methods to detect the service performances of operated composite insulators. In this paper, several advanced technologies were introduced to check the performances of in-serviced composite insulators. The macroscopic properties were mainly detected by means of X-ray digital imaging system, ultrasonic phased array (UPA) and hydrophobicity measurement. In addition, the microscopic properties were analysed by the way of scanning electron microscope (SEM) observation, microscopic infrared spectral imaging system and thermogravimetric (TG) analysis. It was believed that defects such as micro-cracks, gaps etc. could be earlier and quickly found by using these detection techniques, thereby avoiding power failure accidents of the transmission lines.
