摘　　要：综合分析国内已投入运行的贯流式水轮机资料,研究了水轮机比转速与转轮叶片数和工作水头之间的关系,并通过回归分析的方法,综合考虑水轮机转轮叶片数和工作水头对比转速的影响,得到了相应的比转速统计公式。The relationships between the specific speed, the runner blade number and the operating head are analyzed based on the operation data of bulb turbines in China. The specific speed statistical formula is achieved through the regression analysis which considers the effects of runner blade number and the operating head.

关 键 词：比转速 工作水头 贯流式水轮机
