Simple and short flow process, have not required primary sediment pond, secondary sediment pond and aeration pond, and low cost for construction;

工艺简单，处理流程很短，不需要设初沉池、二沉池和曝气池等，建设费用低；

But gas flow rate is too big, but will make arc beam are short and heat loss increased ability to cut down to make cutting process, cannot proceed.

但气体流量过大，反而会使弧柱变短，损失热量增加，使切割能力减弱，直至使切割过程不能正常进行。

When gas flow rate quickly decreases, there will appear a short period of stratified flow in the transient process of the slug flow.

当气体流量突然降低时，在段塞流的瞬态变化过程中则会出现短时间的分层流。
