摘要：
The method involves measuring hydrogen permeation in the tubes by mass spectrometry, wherein the tube is inserted into a high or ultrahigh vacuum device in which a mass spectrometer and a total pressure gauge are located. H2 or H2 and inert gas mixtures are circulated inside the tube at the required partial pressure. The tube is then heated and the appearance of H2 outside the tube is observed. The flow thereof inside the tube and emergence time, called permeation time, are determined based on permeation curves. The emergence time of the first microcrack is also determined.
摘要（中）：
该方法包括通过质谱法测量管中的氢渗透，其中将管插入其中定位有质谱仪和总压力表的高真空或超高真空装置。 H2或H2和惰性气体混合物以所需的分压在管内循环。 然后将管加热并观察管外的H2的外观。 根据渗透曲线确定其在管内的流动和出现时间（称为渗透时间）。 第一个微裂纹的出现时间也是确定的。
