| 摘 要： | 在内夹磁弹性单斜地层中,下界面不规则变化时,研究水平偏振剪切波的传播,该地层夹在两个半无限磁弹性单斜介质之间,得到了闭式的色散方程.不计磁场及介质界面的不规则性,该色散方程与三层介质中经典方程相一致.图示了磁场和界面不规则深度对相速度的影响.

| Abstract: | The propagation of horizontally polarised shear waves in an internal magnetoelastic monoclinic stratum with irregularity in lower interface was studied.The stratum was sandwiched between two magnetoelastic monoclinic semi-infinite media.Dispersion equation was obtained in closed form.In absence of magnetic field and irregularity of the medium,the dispersion equation agrees with the equation of classical case in three layered media.The effect of magnetic field and size of irregularity on the phase velocity h... |
