摘要
本文重点阐述了本人在探索过程中遇到的疑难问题及解决问题的有效方法:消除电子流对高压系统的影响,负高压的产生和提高荷载能力,磁场反相,离子信号反向和自动控制的改造。
Difficulties in the project and the methods of how to overcome them have been given in the paper: excluding effect from electron for heigh voltage plate system, construction of negative heigh voltage system, reverse of magnetic field, redirection of ion signal, and reconstruction of automatic-control system.
