介绍了航天仪器、航天飞机机舱、发动机等空间裝置的出气情况.出气测量是在大型真空容器中进行的.就航天飞机而言,出气数据是从轨道上机舱环境中间断测出的.其化学组分用质谱计测出、这些数据及时地为航天器的设计和性能的改进提供了依据.今后,随着航天飞机的充分利用,有可能提出用于轨道中的有效载荷的出气不再经真空容器测量的方法.在多数情况下,轨道上的出气特性可以利用文中的数据进行估算. Outgoing gas conditions for space devices such as aerospace equipment, space shuttles, engines, etc. Outgoing gas measurements are carried out in large vacuum vessels, where the gas data is measured discontinuously from the orbital environment of the orbit. The components were measured by mass spectrometry and these data provided timely basis for the design and performance improvement of the spacecraft. From now on, with the full utilization of the space shuttle, it is possible to propose that the outlet for the payload in the orbit should no longer be Vacuum Vessel Measurements In most cases, the outgassing characteristics of the orbit can be estimated using the data in the text.
