本SAE航空航天信息报告（AIR）提供了环境控制系统（ECS）设计中的核、生物和化学（NBC）保护注意事项。旨在让ECS设计师熟悉该主题，以便了解在需要NBC保护的情况下进行ECS设计需要哪些信息。这并不是对NBC保护的彻底讨论。这样的文件会很大，而且会被保密。将更详细地讨论与ECS设计师更相关的NBC保护主题。 本文简要讨论了外围设备感兴趣但ECS设计师应注意的问题。只讨论了核爆炸的辐射方面。术语CBR（化学、生物和放射性）已被用于与NBC进行对比，以表明仅讨论核爆炸的放射性方面。这实际上是一个更准确的术语来描述本文的主题，但NBC已在飞机行业中得到更广泛的应用。

This SAE Aerospace Information Report (AIR) provides Nuclear, Biological and Chemical (NBC) protection considerations for environmental control system (ECS) design. It is intended to familiarize the ECS designer with the subject in order to know what information will be required to do an ECS design where NBC protection is a requirement. This is not intended to be a thorough discussion of NBC protection. Such a document would be large and would be classified. Topics of NBC protection that are more pertinent to the ECS designer are discussed in more detail. Those of peripheral interest, but of which the ECS designer should be aware are briefly discussed. Only radiological aspects of nuclear blast are discussed. The term CBR (Chemical, Biological, and Radiological) has been used to contrast with NBC to indicate that only the radiological aspects of a nuclear blast are being discussed. This is actually a more accurate term to describe the subject of this paper, but NBC has become more widely used in the aircraft industry.
