超高真空技术的研究和它在应用方面的研究在真空技术的全部范围内所占的比重年年增加,这点各位读者是知道的。回顾,在10年前的1953年,D.Alpert在应用物理的杂志上发表了“超高真空”的获得和测量的全部情况,当时我国的真空技术工作者似乎还末注意到。可是作者当时虽然正在研究 It is well known to readers of ultra-high vacuum technology and its application in research that the proportion of vacuum technology increases over the years. Recall that in a decade ago, in 1953, D. Alpert published all the facts about the acquisition and measurement of “ultra-high vacuum” in the Journal of Applied Physics, when vacuum technologists in our country did not seem to notice either. However, although the author was studying at that time
