超高真空扩散泵油极限真空测试条件的探讨
The wake shield facitity(WSF) extreme high vacuum system makes use of the property that its orbiting velocity is several times higher than the ambient atmosphere s thermal velocity,leading to a very high pumping by space,hence a rarefaction region up to extreme high vacuum is produced in the wake rigion of WSF.
