The results show that for the common pump control methods, the third power relation between the pump rotate speed(water volume) ratio and the shaft power ratio is not true;
分析结果表明，对于常用的水系统控制方式而言，水泵转速（流量）比与轴功率比的三次幂关系不成立；
In this range of air-water ratio the flow rate of mixture slightly decreased, the axial power increased linearly and the pump efficiency increased parabolically with a rise in effective head.
在稳定工作区范围内，不同的含气量条件下，随着排出压头的增加，混合液总量稍有下降，轴功率直线上升，效率呈抛物线变化。
The water utilization ratio and benefit from power generation have been low, especially in flood season, since the Feilaixia Water Project has been put into service in 1999.
飞来峡水利枢纽运行以来，始终表现出水量利用率低、发电效益低的状况，汛期尤甚。
