Authors: Ji X W , Zhou Y 
Published: June 2021

Abstract
The key problem to improve the efficiency of solar cells by using the effect of surface plasmon is to select the parameters such as the material, shape, size, surface coverage, and the film thickness correctly. Much effort has been devoted to one-dimensional periodic arrays of slits and two-dimensional periodic arrays of holes with different shapes. However, little attention has been paid to the arrangement of the periodic arrays. In this article, we mainly analyze the scattering of gold circular hole arrays arranged in triangles, squares, rectangles and circles with the same thickness, aperture and period, and the results shows that scattering is affected by the arrangement of hole array. This will have certain potential significance to design metal dielectric structure properly for improving the absorption rate of photovoltaic devices.

Authors: Ren Shenggang , Ji Xiaohan 
Published: June 2021

AbstractIn view of the dual background of high-quality economic transformation and low-carbon economy, this paper treats energy-saving and carbon reduction policy for key energy users as a quasi-natural experiment, and empirically investigates the causality and internal mechanism of the front-end control environmental regulation on the export product quality of manufacturing firms. Utilizing the propensity score matching plus difference-in-differences (PSM-DID) method, and based on the export panel data of manufacturing firms, this research provides more in-depth and robust evidence that the policy has led to a significant improvement in export product quality among regulated firms. Furthermore, it is revealed that technological innovation is the driving factor and the positive effect is more pronounced for processing trade firms. The conclusions enrich the evidence for the Strong version of Porter hypothesis, clarifying that the front-end control environmental regulation based on key energy users in developing countries can achieve the double dividend of environmental protection and quality upgrading, thus provide policy implications accordingly.

Published: June 2021

Abstract
With the rapid development of cities, the problem of public transport congestion is becoming more and more serious, which affects the commuting punctuality and ride experience of workers. Shared bus has the characteristics of flexible route, comfortable ride and high punctuality rate, and is developing rapidly. In order to save energy and reduce emissions and reduce the impact of vehicles on the urban environment, shared buses are mostly electric buses with new energy sources. As the new energy electric bus is limited by the range and the uncertain demand of shared bus passengers, it is particularly important to plan the driving route in advance. This paper takes typical shared bus routes in LG City as an example, and carries out operation route planning on Visual C++ platform. Plan bus routes according to road conditions and passenger travel needs. The scheme shows that the Floyd algorithm can optimize the shared bus route, ensure sufficient power operation, effectively reduce the company’s operating cost, and assist the decision of route scheme. The research results of this paper have practical guiding significance and reference value for the sustainable development of urban commuting in the future.

Published: June 2021

Abstract
Energy consumption and climate change have become an urgent task for economic and social development around the world. Building energy consumption and the indoor environment are largely influenced by users’ behaviours. Recently, more and more attention has been paid to users’ behaviour towards energy saving. By issuing questionnaires, this paper investigates the relationship between energy saving willingness, energy saving perception, and energy saving behaviour of office workers. The result shows that psychological factors such as that environmental values, energy saving knowledge, perception of behaviour control, and preference can indirectly affect employees’ energy saving behaviours. Psychological ownership and subjective norms have no obvious effect on promoting energy-saving behaviours. Besides, factors of policy, atmosphere, and publicity have significant effects on energy saving behaviours. Factors such as working age, education, and occupation can significantly promote employees’ energy-saving behaviours.

Authors: Wang Cheng gong , Liu Juan juan 
Published: June 2021

Abstract
Based on the evolutionary game theory, this paper constructs a game model between the government and power battery manufacturers with the aim of promoting the innovation of recycling technology to achieve sustainable development of energy and environment. The effects of penalties and subsidies on the behavior of power battery manufacturers in adopting green innovation technology strategies under unilateral and bilateral government policies are compared. Numerical simulations are used to verify the validity of the model and conclude that: penalties and subsidies can change the final choice of power battery manufacturers only when a certain threshold is exceeded; penalties can make power battery manufacturers adopt green innovation technology strategies more steadily than subsidies at an earlier stage when the green innovation technology surplus is negative; the number of recycling and the degree of technological innovation are also important factors affecting the evolutionary process of power battery manufacturers. Meanwhile, the above conclusions can provide some suggestions for the government to effectively manage the recycling of waste power batteries.

Published: June 2021

Abstract
In the rotor passage of tidal energy hydroelectric unit, there is a tip leakage problem between rotor and runner chamber. In order to research the flow characteristics of tidal energy hydroelectric units and explore the control method of tip leakage, based on the experimental data of NACA0009 hydrofoil, the SST-CC turbulence model was used for numerical simulation and compared with the experimental results. The characteristics of tip leakage flow and vortex were analysed under different hydrofoil shapes and gap widths. The results show that the rounded hydrofoil can effectively control the generation of tip separation vortex, but the rectangular hydrofoil has higher vortices coefficient and lower pressure coefficient in the downstream section; the tip leakage amount will increase with the increase of gap width; the tip vortex intensity will increase first and then decrease, and cavitation may occur when the vortices is maximum. The results can provide reference for studying the control method of tidal energy hydraulic machinery clearance leakage.

Published: June 2021

Abstract
In recent years, the urbanization process in counties has been accelerated due to the support of national policies. The depth and breadth of land use changes in counties have been strengthened, and the value of ecosystem services has been significantly degraded. In order to realize the sustainable development of county ecological environment, it is especially urgent to grasp the impact of different land use types in the county on the value of ecosystem services within a certain period of time. Based on the interpretation of remote sensing satellite images to obtain county land use classification data, the changes in the value of ecosystem services in Nanping City between 1995 and 2015 were explored in depth. The results of the study showed that the total value of ecosystem services in each region changed significantly in different time periods, among which, in 1995, the total value of ecosystem service types in Jian’ou City was the highest. In 2015, the value of ecosystem services in Songxi County decreased the most, amounting to 13.98 billion yuan, while other regions had different degrees of increase. Each regional service type has the highest value of functions such as soil formation and protection, water conservation, gas regulation and biodiversity conservation, while all the food production functions have the lowest value.

Authors: zheng Huang , Yanting Zhang , Hao Zhang , Lin Wang , Jingyu XU , Guangzhi Zhang 
Published: June 2021

Abstract
EGS system is a single-layer heat exchanger system. Because of its output requirements, the temperature drop of the heat exchanger layer is very significant in the expected production stage. At the same time, due to the uncontrollable conditions of the storage tank, the generation of calorific value can not be accurately controlled, so the optimization of the existing EGS heat transfer research is not comprehensive. The solution to this problem is to design a three-tube and six-control EGS technology, which is based on the structure of multi-layer heat exchangers. This technology can control the stratified flow, ensure the medium production, avoid the problem of large temperature gradient in the heat exchanger layer caused by large single layer flow, and provide some reference for conventional and unconventional oil and gas co-production technology.

Abstract
The enrichment law of desserts in Xujiahe formation of Sichuan Basin has become the core problem of tight sandstone gas reservoir. In view of this problem, taking the member 2 of Xujiahe Formation in Yingshan area of Sichuan Basin as an example, the author analyzes the main factors of enrichment of natural gas through the analysis of the basic geological features of sedimentary environment, reservoir, hydrocarbon source, structure and reservoir formation, and then discusses enrichment mode of natural gas. The results show that the reservoir forming conditions of member 2 in Yingshan area are superior, and the widely covered source rocks are developed, and the source rocks have good hydrocarbon generation potential. The sand bodies in the delta front with thick layers are deposited in member 2 of Xujiahe, which is distributed in large area, which lays the foundation for the development of high-quality reservoirs. The reservoir space types are various, mainly mainly including primary intergranular pores, dissolution pores and micro fractures, and the reservoir has good physical properties. The accumulation of natural gas in Yingshan structure is the result of coupling of the following factors: the development of high-quality reservoir controls the distribution of natural gas; the structural background is conducive to the enrichment of natural gas; the good matching relationship between faults and traps controls the differential accumulation of natural gas in the reservoir.

Abstract
With the gradual maturity of solar heating system, more and more houses are equipped with solar heating equipment for heating. In view of the heating effect of the movable plate house, this paper selects the coldest monthly average temperature of -15 °C in Jinan as the external condition, designs the wall embedded heating coil with water as the medium, and uses CFD simulation software to establish the geometric model of the temperature distribution of the house in 7 hours after 10 pm. The simulation results show that when the overall wall is covered with heating coil, the nighttime temperature of the indoor personnel rest area is above 7 °C without considering the heat transfer effect between the personnel themselves and the internal space of the house. If the wall is covered with heating coil, the indoor average temperature will be no less than 12 °C. Solar energy contribution rate can reach more than 43.15 %, energy saving effect is obvious.

Published: June 2021

Abstract
Three petroleum degrading strains were obtained from oily sludge and denoted as A2 (Pseudomonas putida), A4 (Acinetobacter calcoaceticus) and L5 (Sphingomona sp). Crude oil degradation experiments were conducted to investigate the degradation performances of the strains and their bacterial consortium(C) on crude oil. The petroleum degradation rates of A2, A4, L5, and C were 42.8%, 48.01%, 26.56%, and 81.07%, respectively, after 28 days of cultivation, illustrating the removal of petroleum hydrocarbons by the bacterial consortium had a synergistic effect. The bacterial consortium was used to remediate oil contaminated soil in laboratory and the remediation results of the different microbial addition methods-free bacterial consortium (TB), biochar-free bacterial consortium (TB-BC), and biochar-immobilized bacterial consortium (CTB) were compared. The results showed that biochar was beneficial to the colonization of degrading bacteria in the soil, and the number of microorganisms, dehydrogenase activity, and intensity of soil respiration in the CTB treatment were considerably improved compared with those in the other treatments. The removal rates of petroleum hydrocarbons were 18.0% and 32.51% higher than those of the TB-BC treatment and the TB treatment, respectively, indicating that the biochar-immobilized bacterial consortium had a synergistic mechanism of bioaugmentation and biostimulation for the removal of petroleum hydrocarbons.
