一、试验情况简介进行长寿命电子束管的研试工作,需要有一个快速确定电子束管寿命试验的方法,使能迅速获得研试的结论,这是容易理解的。我们试图以上海钢研所的~#7404镍钨钙,代替原来的硅镍作为电子束管阴极端面的基金属,希望能及早了解其寿命情况,特参考了《电子管的加速寿命试验方法》(北京电子管厂)、《常应力加速寿命试验》(中国科学院数学研究所)、

I. INTRODUCTION TO THE TEST It is easy to understand that to conduct a long-life electron beam tube test, a method to quickly determine the life of the electron beam tube test should be provided and the conclusion of the test can be quickly obtained. We tried to Shanghai Institute of Steel # # 7404 nickel tungsten calcium, instead of the original silicon-nickel cathode tube as the electron end of the metal, hoping to understand its life expectancy as early as possible, with reference to the “accelerated life test tube method” ( Beijing Electronic Tube Factory), “the normal stress accelerated life test” (Institute of Mathematics Chinese Academy of Sciences),
