  1. So re oxides has two form existence, one is concentrate on the matrix equiaxial crystal grain boundary as a micron particles and the other is distributed in matrix crystal dispersively as the nanometer particles compared the electron emission performance of mo - la2o3, mo - ; la2o3 - y2o3 and mo - la2c > 3 - sc2o3 cathode, the mo - la2o3 - sc2c > 3 cathode show excellent electron emission character

    上述研究表明不論是在稀土?鉬陰極還是在稀土?鎢電極中，稀土氧化物的存在形式有兩種，一種是微米級的顆粒偏聚于晶界處，另外一種是彌散分佈於基體晶粒的納米小顆粒。
