This method can gain a better result on treatment of waste gas of xylene with low concentration and big flow rate. The highest removal rate of xylene reaches at 87.4%.
该方法对低浓度、大流量的二甲苯废气能达到较好的去除效果，最高去除率可达87．4%。
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 the water content increases, the motion of small particles is obstructed evidently, and the flow rate drops greatly. But the flow rate of big wet particles rises first drops afterwards.
在研究含水量对颗粒质量流率的影响时发现：随着含水量的增加，小颗粒的运动明显受阻，质量流率大大降低，而大颗粒的质量流率会出现一个先升后降的过程。
