Aimed to decrease damping coefficient and enhance pump's dynamic performance, a method for reducing the radial plunger pump stator forces was developed by analyzing the type JBP-63 pump stator forces.

为了降低阻尼系数进一步提高泵的动态性能，通过对JBP-63型径向柱塞变量泵定子受力仿真分析，研究了减小径向柱塞液压泵的定子不平衡力的方法。

And so instead of defining efficiency the way you've got it written there, I'm going to define what's called something different for a refrigerator which is called the coefficient of performance.

现在我们不用,效率的那个定义，我给出一个,有关制冷机的,新的定义,叫做制冷系数。
