起晕电压随着气压的降低(海拔高度的增加)而降低。
And the inception voltage decrease with reduction of air pressure (increase of altitude).
结果表明：喷嘴外径增大，起晕电压和击穿电压升高。
Test results show that the corona's onset and breakdown voltage both rise with increasing OD of the nozzle.
负极性电晕起晕电压先升高后降低，电晕特性变化很小。
The corona inception voltage produced by negative polarity increased at first and then decreased, and corona characteristic has little changes.
文中还针对海拔对管母线起晕电压的影响进行了讨论，给出了工程适用的海拔校正方法。
In addition, the influence of altitude on corona onset voltage of busbar is also discussed, and altitude correction method used in the project is suggested in this paper.
