depressed collector meaning in Chinese
降压集电极
降压收集极
Examples
- The multistage depressed collector ( mdc ) is an important method of improving the twt efficiency
采用多级降压收集极( mdc )是提高行波管效率的重要方法。 - To make pic ( particl - in - cell ) simulations . to set up models of guns and magnetic field and simulate them in the vacuum and plasma , respectively . we found that plasma held back part of space charge effects and improved trajectory of electrons . but beam would oscillate and became instable as accretion of plasma density . by simulating again and again , we draw a conclusion magic could n ' t work when plasma density was more by far than beam electron density . at last a four - stage depressed collector was simulated
建立电子枪和聚焦系统模拟模型,分别在真空和填充等离子体条件下进行模拟。发现填充等离子体能补偿部分空间电荷效应,改善电子束包络轨迹,提高电子的流通率,但是随着等离子体密度的增大,束电子会出现振荡不稳定性,遗憾的是通过反复多次模拟发现本文所用粒子模拟的代表性软件magic无法用于模拟等离子体密度远高于束电子密度的情况。 - To design multistage depressed collectors . to classify electrons by their speeds , electrons with high energy are collected by low potential and those with low energy collected by high potential ; to try to avoid second electrons " emission . besides those air pump system was introduced briefly . 4
将电子按速度分类,高电位收集动能小的电子,低电位收集动能大的电子,使收集极几乎不消耗能量,同时尽量避免二次电子的发射,保证行波管的工作稳定性,此外还简单介绍了下气体电动态系统。
