Subsequently, the optimized technology was successfully scaled up to 〓 pilot bioreactor scale by using the parameter simulation method. The scale-down strategy was applied to the 100〓 fermentation tank to ascertain that the determining factor which affects metabolic flux distribution reasonably had changed to the dissolved oxygen control. After resolution of the DO limitation, the optimized technology inhibited the shift on 100〓 production scale correspondingly, notable commercial returns was gained as a result.

随后基于过程参数拟合的方法成功地将抑制代谢流迁移的新工艺放大到12〓规模，并通过规模缩小证实了100 〓生产规模的发酵过程中限制代谢流合理分配的限制性因素已经发生了变化，此时DO的控制成为优化的前提，通过改善供氧条件之后优化的工艺在生产规模也成功的克服了代谢流的迁移，取得了显著的经济效益。

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。
