课题研究组 meaning in English

independent task force

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
本研究采用高分辨扫描电镜、透射电镜对稀土钼钨阴极材料的显微结构进行了系统研究；利用本课题研究组设计研制的电子发射测量仪对la2o3 - mo ， la2o3 - sc2o3 - mo ， la2o3 ? y2o3 - mo三种阴极(以下称镧?钼阴极、镧钪?钼阴极、镧钇?钼阴极)的发射性能进行了测量；利用经改造后的俄歇电子能谱仪“原位”分析了发射性能较好的镧钪钼阴极在不同温度下表面活性元素的变化情况。
