  1. Based on physical experiments, establishing mathematical model, carrying on theoretical calculations, and contrasting experimental results with theoretical ones, it turned out that under the same initiate flow rate, the quicker the closing of the ball valve, the longer the stable time when the liquid gets to vaporizing pressure, and the bigger the water hammer in water interception collision ; under the same closing velocities of the ball valve, the larger the initiate flow rate, the longer the stable time when the liquid gets to vaporizing preesure, and the bigger the water hammer in water interception collision

    在試驗研究的基礎上，建立了含氣水錘數學模型，進行數值計算，並與試驗結果進行了比較，結果表明，在管道初始流量相同的情況下，球閥關閉速度越快，液體達到汽化壓力凡時穩定的時間越長，彌合水錘壓力也越大;在球閥關閉速度相同的情況下，管道初始流量越大，液體達到汽化壓力凡時穩定的時間越長，彌合水錘壓力也越大。
