| 摘 要： | 运用稳态逐次替换法，研究了不同渗流方式下弹性液体不稳定渗流压力波的传播规律。发现在平面平行渗流，平面径向渗流和球面向心渗流三种渗流方式中，以球面向心渗流方式下的压力波传播速度最快，平面平行渗流压力波传播速度最慢，压力波传播同样的距离所需时间，平面平行渗流是平面径向渗流的2倍，而平面径向渗流又是球面向心渗流的1.5倍。

| Abstract: | The law of pressure spread of elastic fluid unsteady flow in different low states is derived by using the steady state replacement method.Pressure spread in spherical flow is the fastest among the spherical,radial and linear flow states,and that in linear flow is the slowest among them.The time of pressure spread in linear flow is2times as fast as radial flow,and that in radial flow is1.5times as fast as spherical flow,when distances of pressure spread are equal a-mong them. |
