  13. This research has studied the microstructure of cathode materials systematically by the means of high resolution transmission electron microscopy and scanning electron microscopy, surveyed the electron emission performance of la2o3, - mo, la2o3 - y2o3 - mo, la2o3 - sc2c > 3 - mo cathode with the self - designed electron emission surveyor and analyzed the elements changing of the surface of mo - la2o3 - sc2c > 3 cathode in - situ. while it was heated to different temperature. at last, the relationship of the microstructure of cathode, diffusion of active matter and electron emission performances has been discussed

    本研究採用高分辨掃描電鏡、透射電鏡對稀土鉬鎢陰極材料的顯微結構進行了系統研究；利用本課題研究組設計研製的電子發射測量儀對la2o3 - mo ， la2o3 - sc2o3 - mo ， la2o3 ? y2o3 - mo三種陰極（以下稱鑭?鉬陰極、鑭鈧?鉬陰極、鑭釔?鉬陰極）的發射性能進行了測量；利用經改造后的俄歇電子能譜儀「原位」分析了發射性能較好的鑭鈧鉬陰極在不同溫度下表面活性元素的變化情況。
  14. Depth profile acquired with aes has shown that excellent emission character owns to the yielding of the surplus la. analysis the active element concentration on the mo - la2o3 - sc2o3 cathode during it heated. results show la and o diffuse rapidly above 1000 ?, but diffusion rate of o gets slow above 1250 ?, so surplus la maybe produce at this temperature

    而在高於1250時，鑭含量依然上升，而氧含量變化已經不大，故可以認為這是超額鑭生成的溫度，元素鈧在從800加熱到1290 ，其含量基本沒有變化，說明在這種材料中，鈧元素向表面的擴散不明顯。
