中文摘要：

空间辐射环境是飞行器失效的主要原因之一，由于空间辐射环境的复杂性，以及飞行器在空间活动的轨道和设计的寿命不同，飞行器需要的抗辐射屏蔽也不同。我们以卫星的地球同步轨道上的电子能谱，对卫星简化模型进行了抗辐射屏蔽的Monte-Carlo计算，并对计算结果进行了实验验证，在此基础上提出一种新的抗辐射屏蔽方法。

英文摘要：

The radiation environment of space accounts much for spacecrafts＇ invalidation. Anti-Radiation shielding methods depend on the environment of space radiation and spacecrafts＇ orbital altitudes as well as their life expectancy. Energy spectra of the geosynchronous orbit and Monte-Carlo simulation calculation are used in simulating simple satellite model＇s shielding effects. Our calculation results are supported by experiments. A new view on anti-radiation shield design is then presented.
