The sterilization results of the positivecorona discharge plasma are better than the that of the negative one with the same other discharge conditions.
在其他放电条件相同时，正电晕的杀菌效果优于负电晕。
2
The corona voice strengths and levels of radio interference produced by positive polarity wire have little changes, and those produced by negative polarity wire increase with temperature.
正极性导线电晕声音和无线电干扰变化都不大；负极性导线电晕声音和无线电干扰都增大。

It was obtained through experiment and simulation that positive DC corona inception voltage and corona ion current under different air pressure and humidity conditions.
