Work by a pair of cavity mesh with each other in motor driver of rotor, next at high speed, and between the volume is constantly changing, so as to constantly pressure increase pressure condensed.
The theoretical analysis and experimental results show that the elliptic cavity is good for falling film evaporation and can effectively enhance the speed of evaporation and heat transfer efficiency.
理论分析和实验结果表明，椭圆腔板束有利于降膜蒸发，能有效地提高蒸发速度和传热效率。

The cutters used in high speed machining(HSM) have poor rigidity, therefore the method fits to HSM of die cavity due to the unfluctuating cutting force characteristic.
