这个能量释放的不平衡，与很多工艺参数密切相关，如等离子弧压缩程度、切割速度及喷嘴到工件的距离等。

This energy release imbalance, closely related with many process parameters, such as plasma arc compression degree, cutting speed and nozzle to the distance, etc.

另外，过大的切割速度和过大的喷嘴高度都会引起切口上下宽度差的增加。

In addition, too much cutting speed and big nozzle height can cause and the increase of the poor incision width.

这个等式是其中一个最有用，因为它允许喷嘴出口速度计算。

This equation is one of the most useful, as it allows the nozzle exit velocity to be calculated.
