抑制栅极

In our experiments, the hafnium films were deposited on molybdenum substrates by radio frequency magnetron sputtering technology, and the barium oxide layers were prepared by the chemical method to simulate the grid structure of traveling wave tubes. Then, the surface phase and compositional change in the grid was studied under high temperature by annealing from 900K to BOOK, which can be used in explaining the suppression mechanism of hafnium film.

实验中，利用射频磁控溅射技术在Mo基底上制备了Hf膜，并利用化学方法制备了BaO涂层以模拟行波管栅极结构，随后在N_2保护下，通过在900K到1300K范围内退火，研究栅极处于高温工作环境下表面相结构和成分的变化，以此解释了Hf薄膜抑制栅极电子发射的工作机理。

I will endeavour to find you some assistance.

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
