带电晕屏蔽管电晕线组的研究，就是在这种背景下应运而生的。
The study on corona wire group with corona shielding tube comes into being under this background.
利用电晕线支撑部分和屏蔽管的静电屏蔽效应，可以改善电除尘器板电流密度分布，减弱反电晕，并可得到高电压低电流的安全运行状态。
By using this kind of shielding effects, the electric current density distribution can be improved, the back-corona can be reduced and the high voltage and low current state can be obtained.
该光电二极管安放在一个电屏蔽的暗箱中。
The photodiode is placed in an electrically shielded dark box.
