In this paper, we analysed supersonic speed flow of oil steam with using Air Dynamics and required the flow law of oil steam at the edge of the nozzleend.
本文用气体动力学分析了油蒸汽的超音速流动，得到扩散泵喷嘴出口油蒸汽的流动规律。

Adopt ceramic nozzle can be the nozzle, that is set to zero height vent end direct contact with the surface is cut, can achieve very good result.
采用陶瓷外喷嘴可以将喷嘴高度设为零，即喷口端面直接接触被切割表面，可以获得很好的效果。
