扩散阴极 meaning in Chinese
diffusion cathode
Examples
- Since non - uniform electronic emission , poor recovery after ion bombardment and too expensive of sc2o3 , scandate cathode has not been vastly used
但含钪扩散阴极存在发射均匀性不好、抗离子轰击性差以及价格昂贵等因素的制约而没有获得广泛的应用。 - Scandate cathode has outstanding properties of high emission at low work temperature . it ’ s the only thermionic cathode which can suffice to the development of new electronic device ’ s requirement
含钪扩散阴极具有极其优异的低温高电流密度的电子发射的能力,是目前唯一能满足新型电子器件发展要求的热阴极材料。 - In this dissertation , eu2o3 - sc2o3 , y2o3 - sc2o3 co - doped tungsten powders and impregnated cathodes related to these powders have been prepared by pressing , sintering and impregnating for the first time
本论文首次制备了复合稀土eu2o3 - sc2o3 、 y2o3 - sc2o3掺杂的钨粉,通过粉末压制、烧结和基体浸盐的工艺制备了相应的复合稀土/氧化钪-钨基扩散阴极。
