| 中文摘要: |
| 利用自行设计的专门实验设备，对脉动压力在缝隙中的传播规律进行了实验研究。结果表明，1) 缝隙内水体流动系受进口边界条件控制的流动；2) 缝隙末端开口时，缝隙中脉动压力振幅沿程减小；3) 缝隙末端封闭时，缝隙内脉动压力振幅沿程增加；4) 缝隙中的脉动压力在传播过程中均出现倍频放大现象。 |
| 英文摘要: |
| The laws of fluctuation pressure propagation in fissures are studied experimentally in lab. Some results are obtained:1.the flow pattern in fissures is controlled by the boundaries of entrance;2.the amplitude of fluctuating pressure will be reduced in the passage of fissure if the exit is open, but it tends to increase in case the exit is blocked; 3.the phenomenon of amplitude multiplier due to multiple frequency is found in the process of pressure propagation. |
