摘　　要：文章介绍了航天器防护高能带电粒子的一种新方法——利用磁鞘进行主动防护。阐述了磁鞘防护高能带电粒子的基本原理,分析了其在工程应用上的可行性,并提出了磁鞘的一种设计方案。针对这种设计方案进行了数值分析计算,结果表明该方案可以有效防护0.15MeV以下的电子。In this paper,a new method is proposed for protecting spacecraft against high-energy particle irradiation by using a magnetic shielding system. The principle of the magnetic shielding system and the feasibility in its engineering applications are discussed. A design of such a system is shown with relevant calculations. The results indicate that the design is effective in protecting spacecraft against space electrons up to 0.15 MeV.
