中文摘要:
      热阴极电离真空规 (简称电离规) 在高真空测量领域有着广泛的应用。介绍了电离规在卫星真空热试验中的使用情况, 并进行了分析。在卫星真空热试验中, 分别在星表及星上布置了电离规, 使用过程中发现星表电离规在整个试验期间测量正常, 而星上电离规在试验开始一段时间后均会失效, 且故障现象一致, 通过对比分析发现是规管内部受有机物污染所致。
英文摘要:
      The hot cathode ionization vacuum gauge (ionization gauge) has a wide range of applications in high vacuum measurement. The application of the gauge in satellite thermal vacuum test was introduced and analyzed. In satellite thermal vacuum test, the gauges were installed on the satellite and trestle. It was founded that the gauges on trestle worked normally throughout the test, but the gauges on satellite failed after a period of time. The failure phenomena were the same. It was founded that the cause of failure is contamination by organic substance.
