1 绪言(略) 2 工作环境 在文献[6]中,琼森(Johuson)对空间环境作了相当仔细的介绍。在某种程度上说,随着材料在宇航器或卫星上所处的位置不同,它们可能承受着高真空、质子、电子、γ射线及紫外线的幅照、微陨石的轰击、失重、极限温度热冲击和热循环。在地面储存或准备发射期间以及发射时可能发生更深一层的问题。即是由于水汽或大气腐蚀 1 INTRODUCTION (Slightly) 2 Working Environment In [6], Johuson gives a very careful introduction of the space environment. To some extent, as the materials are located on spacecraft or on satellites, they may be exposed to high vacuum, proton, electron, γ-ray and ultraviolet radiation, meteorite bombardment, weight loss, temperature extremes Thermal shock and thermal cycling. A deeper problem may occur during ground storage or preparation for launch and launch. That is due to water vapor or atmospheric corrosion
