Abstract

Features are considered of the construction of closed equations for the mean field of acoustic waves with discontinuous profiles in a randomly inhomogeneous medium. Different approaches to obtaining such equations are compared. It is shown that despite the smoothing of profiles on average, a discontinuity in a profile should be considered before averaging. An exact expression is obtained for the mean field of the initial N-wave.

随机非均匀介质中不连续声波的平均场

考虑了随机非均匀介质中具有不连续剖面的声波平均场闭合方程的构造特点。比较了求得此类方程的不同方法。结果表明，尽管平均剖面平滑，但在平均之前应考虑剖面中的不连续。得到了初始n波平均场的精确表达式。
