6)  Extreme high vacuum
极高真空
1.
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.
轨道分子屏真空系统,是利用分子屏轨道飞行速度远大于轨道环境大气的平均热运动速度,使空间环境对分子屏产生理想的抽速,在尾部形成气体分子的稀化区,达到极高真空。
