trajectory of electron meaning in English

电子轨道

The trajectory of electron , the electronic energy , emittance and the bunch length in the accelerating process are presented . primary properties parameters are obtained on different positions
虽然第一加速段之前的漂移距离较长，但缩短该漂移段距离的模拟表明对提高束流性能的作用不大。
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。
