fluctuation test meaning in Chinese

仿徨变异测验
起状试检
彷徨变异测验

In this paper , it is introduced to the influence of cavitation factor , measurement taps , sampling frequency and sampling time on the test result in pressure fluctuation test of the water turbine
摘要介绍了水轮机压力脉动试验时空化系数、测量位置及测点、信号采样频率及采样时间等因素对试验结果的影响。
At same time , author suggests to change cavitation factor to important operation condition during pressure fluctuation test so to avoid producing the phenomenon of cavitation stimulus in the prototype operation
同时，建议针对水轮机的重要运行工况，增加不同空化系数下的压力脉动试验，以避免在真机运行时可能产生“空化自激”现象，确保原型机组的安全运行。
