The main points are to represent the utilization ratio of energy as a series of functions of the grain size of feed material and the fineness of discharge al well as the nozzleform.
研究的主要内容是给料粒度与粉碎产物细度和能量效率的关系，以及喷嘴形状与能量效率的关系。

The steam is cooled by the cold engine nozzle, condensing and eventually freezing at the nozzle exit to form icicles.
热蒸汽被喷口边缘冷却、压缩并最终形成了喷口边缘的冰柱。

In addition, plasma jet from the form into consideration, the jet from the gun in diameter is expands outward, nozzle increase in altitude inevitably lead to increased width incision.
