Probability integration method of stochastic media expectation theory, which bases on the foundation of flaccid up-cover terrane and bestraddle of top board, is discontinuous media theory.

随机介质预计理论概率积分法是建立在上履岩层软弱、顶板跨落基础上的非连续介质理论。

The sound wave come from the earth's surface echoed from the interface of the common terrane and the oilness terrane, or the inteface of aquiferous terrane and the gassness terrane.

从地表产生的声波在普通岩层和含油岩层、含水岩层或含气岩层之间的界面上反射。
