燒結陰極 的英文怎麼說
中文拼音 [shāojiēyīnjí]
燒結陰極
英文
sintered cathode-
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
本論文首次制備了復合稀土eu2o3 - sc2o3 、 y2o3 - sc2o3摻雜的鎢粉，通過粉末壓制、燒結和基體浸鹽的工藝制備了相應的復合稀土/氧化鈧-鎢基擴散陰極。The properties of these doped powders, the microstructure and composition of these rare - earth co - doped tungsten matrices and cathodes have been investigated by size analysis, xrd, sem and edax. the electronic emission performances of these cathodes are measured in uhv electron emission surveyor. aes is adopted to analyze the atom composition and diffusion behavior of active elements on cathode surfaces
通過粒度分析、 xrd 、 sem 、 edax研究了摻雜粉末的特性、燒結基體和陰極的微觀結構和成分;用動態真空電子發射測試儀對上述陰極進行了電子發射水平的測試;採用aes對陰極表面原子組成和活性物質的擴散行為進行了研究，分析了陰極發射水平與表面原子組成的關系。The cathodes both of the prepared tungsten - based barium - tungsten cathode and mixed metal barium - tungsten cathode have, not only high current density, but also a long life, simplified procedure and stable performance, and so on. and we made certain two good additives cr2o3 and ni2o3 that make the cathode performance more excellent
2 ）對不同元素配比的二元和三元混合陰極基底的制備工藝和發射性能開展了實驗研究，在增大發射能力，延長壽命和降低燒結溫度等方面有重要進展，取得了有價值的階段成果。
