摘要: 正 (一)引言 我们知道,在真空条件下可以由化学反应产生氧,例如,加热氧化亚铜、氧化锰或过氧化钡等;也可通过真空阀门向真空室内放入纯氧;而通过加热银管向系统内放入高纯氧则是较简便的方法,这是本文所要讨论的内容。当然,更新的获取高纯氧的方法是用氧化钙稳定氧化锆作渗透膜。 (二)实验技术和结果 我们的实验系统如图1所示。它包括抽速为60l/s的三极式溅射钛离子泵(日本

Abstract: A method for obtaining pure oxygen by heating silver tube and its device are described. The mass-spectrums of some gases have been measured, and its partial pressures have been calculated. Corresponding oxygen pressures have been obtained when silver tube was heated to different temperatures. -
