The power coefficient of HFETR is defined and measured.

本文定义并测量了HFETR 的功率系数。

Concept and calculation method of synthetic power coefficient are proposed.

提出了综合功率系数概念及计算方法。

The head coefficient, power coefficient, and efficiency decreased with increasing axial clearance.

随轴向间隙扩大，超小型泵的扬程系数、功率系数和效率都逐渐降低。

The smaller the synthetic power coefficient is, the better overall performance of propulsion system will be.

综合功率系数愈小，推进系统的整体性能愈好。

The results show, for pitch-controlled wind turbines, that power coefficient is higher, and load is lower at high wind speed.

结果表明，变距型风力机风能利用系数高，在高风速时所受的载荷小。
