摘　　要：2009年7月22日,我国长江流域自西向东发生了一次超长时间的日全食。根据日食产生的机制及几何特征,分析了日食对航天器光照条件影响,并给出了典型地球轨道航天器算例。On Jul.22,2009 an exceptionally longtime total solar eclipse took place in China. The path of the total solar eclipse crossed from the west to the east of the Changjiang River＇s drainage area. Based on the principle and characters of the solar eclipse,the effect on the spacecraft＇s lighted condition caused by the solar eclipse,and the examples for spacecraft working on typical orbits around the earth are presented.
