Published: September 2019

Abstract
The representation method for submarine topography is mainly the sounding notations combined with depth contours representation currently, and the sounding notation is the important part of the seabed terrain representation model. The most commonly intuitive and used seabed terrain representation model is the chart. The users understand the sea area through the interpretation of depth notation in chart, which contribute to achieve safe navigation and well-off exploitation. The density of bathymetric notation is specified in various regulations on charting that proposed by the state, thus the arrangement of soundings is only mentioned simply without stating any reason. Based on the characteristics of seabed topography and the features of hydrographic survey, the conditions that the soundings arrangement should satisfied are analysed, two types of soundings notation places which can meet the conditions are induced. Finally, the two arrangements are compared on the representation ability, and accuracy and feasibility of the rhombohedral arrangement are verified better by the results of the statistical calculation.

Published: September 2019

Abstract
Structural analysis usually divides the rigidity performance of floor system into three types: rigid, stiff and flexible.For specific engineering buildings, how to evaluate their rigid performance, there is no uniform regulation in national regulations. Based on the general analysis of the relative specifications and research contents of the rigid performance of the floor, two types of analysis and evaluation methods of the rigid performance of floor system are summarized,type I and type II method.The type I method is more convenient to use.The type II method can directly reflect the the essence of the rigid performance of the floor,but it is more complicated to use.

Abstract
The energy consumed in residential buildings has become a key factor in China. An energy-efficient and low-emission fuel cell co-generation system (FC-CGS) is a promising electric and thermal energy generation technology to enhance the energy-saving effects for residential application. SOFC-CGSs and PEFC-CGSs are the two major types of residential FC-CGSs. This paper aims to analyze the energy-saving effects of FC-CGSs for residential buildings in Chinese hot summer and cold winter areas. Changsha city is selected as an example. This study at first outlines SOFC-CGSs and PEFC-CGSs, introduces the simulation methods and develops a standard family model for simulation, then calculates domestic demands of the system, and finally compares the primary energy consumption and CO2 emissions of FC-CGSs with those of a traditional power and heat generation system based on gas and electricity. The results show that residential PEFC-CGSs offered primary energy reduction of 8.8% in winter. However, the average reductions of primary energy and CO2 emissions of SOFC-CGSs were 15.1% and 9.9%, respectively.

Abstract
The research on the micro-thermal environment of universities is conducive to improving the environmental quality of the campuses, however, there are few related Microscopic empirical research. The research goal of this paper is to take the Dujiangyan Campus of Sichuan Agricultural University as an example to explore the correlation between campus visual landscape elements and micro-thermal environment, and then propose a landscape optimization approach to improve the thermal environment. By way of a panoramic camera, a temperature measuring instrument, and a thermal imager, the panoramic view, air temperature and the surface temperature of the main landscape of 120 sites on the campus were collected through the system sampling method, elements of visual landscape and their spatial distribution were graded and quantified using artificial intelligence image recognition method and ArcGIS. The air temperature was taken as the dependent variable, and the elements of visual landscape and their surface temperature were taken as the independent variables during the experiment to analyze the coupling relationship between the campus micro-thermal environment and the landscape elements by way of the geo-detector. The results show that the campus landscape consists of five major elements: roads, buildings and structures, vegetation, people and vehicles. The distribution regarding the proportion of the field of view has significant spatial differentiation. Among the five visual landscape components, the artificial environment, such as roads, buildings and structures, has a relatively larger impact on the spatial differentiation of the campus thermal environment compared with other factors; The temperature of people, proportion of vehicles and vegetation surface temperature have less explanatory power for spatial differentiation of campus thermal environment; The proportion of the five types of elements and their surface temperature have no significant correlation with the campus thermal environment.

Published: September 2019

Abstract
In this paper, the blade angle modulation method is used to design the unequal distance fan, and three unequal-distance fans with different blade spacing angles are designed. The aerodynamic noise and aerodynamic performance of three unequal-distance fans are analyzed and studied by CFD simulation method. The results show that with the increase of the uneven distribution of blades, the total A-weighted sound pressure level of the fan and the discrete noise of the fan at the passing frequency decrease significantly. The difference between the main aerodynamic performance parameters of three types of non-equidistant fans and equidistant fans is small, which shows that the unequal distance distribution has little effect on the aerodynamic performance while reducing the noise.

Abstract
The Combined Cooling Heating and Power System (CCHP) system can achieve highly efficiency by energy cascade utilization, which is one of the core units of the integrated energy system in the future, with great development potential. Aiming at the complicated operation performance of the CCHP system, an operation characteristic analysis method is studied under multiple modes. Firstly, a typical simulation model of the CCHP system is established, while the energy flow is analyzed. Secondly, an evaluation system considering multi-dimensional indicators such as energy consumption, comprehensive cost and pollution discharge of the system is built. According to the electric and thermal load of a building, the capacity of the main equipment of the system is designed. Furthermore, the energetic, economic and environmental performances under “following electric load” (FEL) mode and “following thermal load” (FTL) mode are quantitively analyzed, comparing with the traditional separated providing system. The results show that this method reveals the advantages and disadvantages of the performances of the CCHP system under different operating modes, thus can provide a reasonable basis for the selection of operational strategies.

Published: September 2019

Abstract
Graphene is a promising reinforcement in metal matrix composites, which has been developing rapidly in recent years. The aim of this paper is to investigate the effect of sintering temperature and holding time on the properties of graphene nanoplatelets (GNPs)/Cu composites prepared by hot pressing. Sintering temperature and time were in the range of 550–750 °C for 0–60 min. A correlation is established between the mechanical properties of GNPs/Cu composites and sintering parameters. The results show that the variations in tensile strength of GNPs/Cu composites are dependent on both sintering temperature and time. With increase of sintering temperature, the tensile strength increases first and then decreases. When sintered at 650 °C for 30 min, the maximum tensile strength of 303 MPa is achieved. The tensile strength of GNPs/Cu composite sintered 30 min at 650 °C is also higher than that of 0 and 60 min.
