The results show that the surface damage, the weight loss and the leakagerate of an O-ring all increase in proportion to its of the time exposed to atomic oxygen.
暴露时间越长,表面形貌受到的损坏越严重、质量减少量越多,泄漏率也就越大。

The effects of surface roughness at different areas of the seal faces on the performances such as gas film stiffness and leakagerate of a S-DGS were studied.
