This paper consider centrifugal force and coriolis force for ideas of Planetary LabCD Valve Model and Single Point Fluid Separation Model, then the relation of critical rotation speed and planetary angle is linear which control parameter of critical rotation speeding in the Planetary LabCD Valve Model and compare with James Lee theory, and define γR in SPFS Valve Model to show the relation of the low rotation speed is linear and is fixed where the high rotation speed for utilizes any rotation speed.

本论文考虑离心力与科氏力之影响，且提出行星式碟片阀门模式与单点流体分离阀门模式两模式，其中行星式碟片阀门模式，其临界转速与行星角之大小近於线性变化，可当於控制阀门之临界转速之设计参数，且比较在阀门设计上考虑行星角来控制阀门临界转速与James Lee之阀门临界转速理论可以得知，从吾人所提出行星式碟片阀门模式可以得到与实验结果相同的趋势。
