太空环境中舱外航天服的外层防护问题

舱外航天服是人类太空探索和活动的基本条件，这里着重论述了太空的各种环境及其对出舱人体外层防护的要求和应用研究并针对太空环境的特点，讨论了各种条件下的防护机制、有效防护的实现以及防护材料应该具备的性状。尤其是文中穿插了实际研究的一些想法和结果．这为出舱人体防护材料的综合功能设计提供了基础。

Issues on the Out-layer Protection of Spacesuit in Space Environment

A spacesuit or EMU(Extravehicular Mobility Unit) is essential for the human being to explore the universe. The different factors of space environment have been listed, and the issues and related researches on the out-layer protection materials for EMU have been discussed fundamentally. On the base of the characteristics of space environment, the protective mechanism in different conditions, the realization of effective protection and the structure and property of the protection materials have also been discussed in detail. Some ideas and results, especially researches are introduced, which can provide foundation for the realization of the multi-functions design and protections of the out-layer materials to be used to EMU.
