Finally the positivecolumn is reached where electrons and ions have equal densities.
最后到达的区域是正柱区，这里，电子和离子具有相等的密度。

Beware of a hall in the positivecolumn two, the East and West, between the two seam position.
殿内正面当心间有中柱两根，在东西次间之两缝位置上。

The results show that the long electrode gap leads to the positivecolumn which is caused by the climbing voltage on the cathode surface due to the accumulation of positive ions.
