In order to reveal how the "social capital" affects the public participation and social governance in the process of community micro-regeneration in China, this paper takes two old communities in Chaoyang District of Beijing as examples, to compare the impacts of various social capital levels on participatory community planning and design. The study proves the significance of community social capital and community self-government for the success of residents’ participation and community regeneration, as well as providing suggestions on how to improve public participation effects by strengthening social capital of communities.展开更多

This demonstration system, which aims at the application in GSM1800 mobile communication base station, consists of a single RF path, i.e. one filter and one LNA, integrated with the pulse tube cooler. The subsystem works at a pass band of 1710-1785 MHz with a gain of 18 dB and at a temperature of 70 K. The accomplishment of such a demonstration subsystem can boost the development of HTS commercial subsystem.展开更多
