摘　　要：对钡钨阴极的制备工艺进行了探讨,并对阴极基底的表面和内部结构与阴极盐成分的检测方法进行了介绍。并在进行大量试验后,得到一种较好的钡钨阴极制造工艺。A kind of manufacture techniques about Ba--W cathodes are introduced in this paper. The measurements of the inner and surface structures of the based metal of Ba--W cathode and aluminate are also introduced. After a lot of experiments, we finally determined Ba--W cathode preparation with an excellent emission.
