| 1 | Anisotropic thermoelectric properties of layered compound SnSe2显示文摘Similar to high performance SnSe thermoelectrics, SnSe2 is also a layered structured semiconductor.However, its anisotropic thermoelectric properties are less experimentally investigated. In this work,Cl-doped SnSe2 bulk materials are successfully prepared, and their thermal stability and anisotropic transport properties are systematically studied. Unexpectedly, different from the theoretical prediction and other typical layered thermoelectric compounds like Bi_2Te_3, the out-of-plane zT_c value is higher than in-plane zT_a for the same composition. The zT value is significantly enhanced by Cl doping. A maximum zT_c of ~0.4 at 673 K is achieved in SnSe_(1.88)Cl_(0.12), twice higher than previously reported Cl-doped SnSe_2 synthesized by the solvothermal method. | Peipei Xu Tiezheng Fu Jiazhan Xin Yintu Liu Pingjun Ying Xinbing Zhao Hongge Pan Tiejun Zhu | 2017 | Science Bulletin2017，62，24： | 4 |
| 2 | Spatial-temporal Evolution of the Urban-rural Coordination Relationship in Northeast China in 1990-2018显示文摘To comprehensively understand the law of urban-rural relationship and propose scientific measures of urban-rural coordinated development in Northeast China,this study uses the coupling coordination degree model and geographically and temporally weighted regression(GTWR)model to analyze the spatial-temporal patterns and the corresponding driving mechanisms of its urban-rural coordination since 1990.The results are as follows.First,the urban-rural coupling coordination degree in Northeast China was very low and improved slowly,but its stages of evolution is a good interpretation of the strategic arrangements of China's urbanization.Second,the urban-rural coupling coordination degree in Northeast China had spatial differences and was characterized by central polarization,converging on urban agglomeration,which was high in the south and low in the north.Moreover,the gap between the north and south weakened.Third,the spatial-temporal evolution of the urban-rural coordination relationship in Northeast China was influenced by pulling from the central cities,pushing from rural transformation,and government regulations.The influence intensity of the three mechanisms was weak,but the pulling from the central cities was stronger than that of the other two mechanisms.Furthermore,the spatial difference between the three mechanisms determines the spatial pattern and its evolution of the urban-rural coordination relationship in Northeast China.Fourth,to promote the development of urban-rural coordination in Northeast China,it is essential to advance urban-rural economic correlation,enhance the government^role in regulating and guiding,and adopt different policies for each region in Northeast China. | WANG Ying CHEN Xiaohong SUN Pingjun LIU Hang HE Jiaxin | 2021 | Chinese Geographical Science2021，31，3： | 4 |
| 3 | Resident's Floor Level Preference in High-Rise Residential Buildings in China:A Case Study of Shijiazhuang City,Hebei Province显示文摘With the constant advance of global urbanization and aggravation of urban construction land scarcity,high-rise residential buildings have become one of the main carriers of urban residential function on account of both land saving and large housing requirement.However,relevant studies on consumers' floor selection preference in high-rise residential buildings,regarding what inherent and regular features and causes it has,are still insufficient,despite that related issues have important practical significance for real estate developers and designers' decision making in terms of dwelling size ratio,floor area,indoor layout,and so on.This study,based on systematic examination of existing domestic and international researches,seeks to make empirical tests and generalization on the above issues from the aspect of 'utility function'(safety,comfortableness,accessibility and economic efficiency) of the living environment that impacted by different floor levels,and floor selection features regarding consumers' social and family structure attributes,as well as the intrinsic correlation between them.The results show the existence of floor level preference in high-rise residential buildings.Its essence is a personalized characterization of consumers' social and family structures' attributes in selecting the 'utility function' of the living environment,as the preference value differs under various attributes including gender,age,income,family members and others. | Sun Pingjun Wang Ying Pang Ruiqiu Song Xinyan | 2016 | China City Planning Review2016，25，2： | 0 |
