摘要(Abstract)：
阐述了离心式水泵在欠负荷运行时,发生在叶轮入口处的回流现象、产生机理及其对汽蚀的影响;并对在回流出现时发生在叶轮叶片上的汽蚀现象和影响因素进行了初步探索。
The backwater phenomenon,producing mecha- nism and influence on cavitation are set forth while pumps are in part-load work.The cavitation phe- nomenon occurring in impellers and influence factors when backwater appears are also disscussed.
