摘要
针对三维非规则弹性海底条件下声传播问题,提出了采用逐次近似法的求解计算方法,并就一个特例给出相应的解析解。结果表明在倾斜海底条件下声传播的水平折射效应,和沿海底界面传播的界面波特点。
Related formulae for solving sound propagation in sea with three-dimensional elastic bottom are given, and the result for one special case had been solved. It shows the horizontal diffraction of sound wave due to inclined bottom, and characteristics of the interface wave.
