electronic emission meaning in English
电子发射
电子放射
Examples
- Auto - electronic emission
自动电子发射 - 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。 - 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
通过粒度分析、 xrd 、 sem 、 edax研究了掺杂粉末的特性、烧结基体和阴极的微观结构和成分;用动态真空电子发射测试仪对上述阴极进行了电子发射水平的测试;采用aes对阴极表面原子组成和活性物质的扩散行为进行了研究,分析了阴极发射水平与表面原子组成的关系。 - This project which is based on the demand of increasing the electron tube ’ s qualities totally and reducing the manufacture cost has done a large amount of investigative work as follows to improve and perfect the technologies for the important part of electron tube manufacture ? the grid surface processing : on the surface processing of the molybdenum grid , the primary purpose is to reduce thermionic emission and secondary electronic emission of the grid . by the constantly experiment and grabbling the different technology routes , we have successfully developed these new technologies on the tac and zrc electrophoresis and electroplating platinum black of the grid , and made its surface cladding quality very stable and reliable
