摘　　要：讨论Ｈｅ－Ｎｅ激光管对空气及氦气的允许漏率，提出用累积法对激光管进行无损检漏，并对其最小可检漏率及特征时间给出具体数据。First, we discuss allowed leakage of He-Ne laser pipe to air and He gas, then the question of the measurement of leakage by using cumulation method is pat forward. Finally, the results are given for characteristic time and the least measurable leakage.

关 键 词：允许漏率 检漏 氦-氖激光管 光电子真空器件
