In this paper  the design method of heliostats field for the scale of 1MW solar power tower plant with latitude of 40.4N at the design point of the noon of spring equinox is introduced  which uses the multiplication of three efficiencies of cosine  atmospheric transmittance and intercept as the preliminary boundary limit to locate heliostats  while the spacing between heliostats is set not only for less shading and blocking  but also for the availability of installation and maintenance of heliostats. Furthermore  its optical performance tested by the software HFLD  is quite good  which has annual average efficiency of 71.36% and design point efficiency of 80%. 2012 IEEE.   数字经济测度研究 学位论文 2008, 2003 袁勤俭 收藏  |  浏览/下载：1/0  |  提交时间：2016/02/14 信息技术产业  市场结构  市场行为  市场绩效  产业组织政策  软件盗版  数字鸿沟  Information technology industry  market structure  market conduct  market performance  industrial organization policies  software piracy  the Digital Divide
