So that the criticalcavitation pressure for judging the happening of reverse water hammer in hydropower station must according to the real evaporation pressure measured from the water in prototype.
因此，要使用电站实测水质的临界空化压力值来作为判断发生断流反水锤的临界压力。

Cavitation phenomenon may be found in this elastic-plastic material. Formulae between the cavity radius and the stretch were obtained. The critical stretch was given too.
