The concept of inputwave impedance is introduced in order to generalize the developed theory to multi-layer medium cases.
接着引入输入波阻抗的概念，把理论推广到多层媒质的情况。

Under the condition of similitude law, the seismic responses of model slopes are investigated with different inputwave kinds, frequencies, excitation directions and amplitudes.
The ability of the retroreflector array to provide psedophase conjugate wave of the inputwave is investigated and the calculated results of different Zernike polynomials aberrations are presented.
