这是我们教育丛书中的一篇论文:在学校和学院中真空科学和技术的理论和实践。 本文第Ⅱ部分研究放气率的测量方法。详细说明所选用材料的测试结果。对用于超高真空的材料,本文还探讨一些减少放气率的方法。 1.序言 在任一个无漏气并达到平衡的真空系统中,压强决定于系统总的放 Here is an essay in our Education Series: Theory and Practice of Vacuum Science and Technology in Schools and Colleges. Section II of this article studies the measurement of the outgassing rate. Detailed description of the selected materials test results. This article also explores some ways to reduce the outgassing rate for materials used for ultra-high vacuum. 1. Introduction In any airtight and balanced vacuum system, the pressure depends on the total system
