水平流体层中声波频散方程式根的计算与分析

Calculation and Analysis of Sound Wave Frequency Dispersion Equation Roots in the Level Fluid Layer

研究了水平流体层中声波频散方程式实根的分布．计算结果表明，在一定频率下频散方程存在一个或多个实根，由实根分布可以预测在水平流体层中导波的传播机制．

In the paper is studied the distribution of the real roots of sound wave frequency dispersion equations in the level fluid layer. The results show that under given frequency the frequency equation has one or several real roots.The distribution of real roots may predict the propagation mechanism of conducting waves in the level fluid layer.
