Particularly necessary to point out that the liquid in the pump body mass flow rate of less than the circumference of the circumferentialspeed of the impeller.
需要特别指出的是，液体质点在泵体流道内的圆周速度小于叶轮的圆周速度。
2
The relation between the number and speed of stall cells and the circumferential stalled region and the main geometric parameters of cascade is described.
描述了失速团数目、失速团传播速度和周向范围与叶栅主要几何参数的关系。
3
The belt's circumferential and the radial mass inertia have a great impact regarding the high speed belt drive and the flexible belt drive.
