摘要(Abstract)：
阐述了多级离心式水泵吸水叶轮在大负荷状况运行时吸水区域的汽蚀情况，以及蒸汽场与欠负荷旋涡之间的关系。对发生在叶轮前吸水短管中的汽蚀现象、产生机理和影响因素进行了初步探索。
The cavitation condition in entrance during part-load work of absorbent impeller is set forth for the multistage centrifugal pump, and relations between the steam field and part-load vortex is presented. The cavitation phenomenon, producing mechanism and in fluence factors in the absorbent pipe are also discussed.
