| 摘 要： | 为准确地确定水管路系统管道内的压力波传递速度，在研究谐振频率测量法和时差域测量法的基础上，对水管路系统中的压力波传递速度进行实验测量。实验结果证明，测得的管路系统的压力波传递速度总是略小于自由场中的声速，且两种方法的测量结果相近、测量精度较高。

| Abstract: | In order to define the velocity of pressure wave propagation correctly in the water piping,the velocity of pressure wave propagation was measured by the experiment on the base of study of the resonant frequency measurement method and the time difference domain measurement method.In the experiment the velocity of pressure wave propagation was smaller than that of sound in the free flied,and it was found that the measurement results of the two methods were similar and the measurements were precise better. |
