sound wave

1.Ordinarily, random thermal jigging of the molecules prevents sound waves from behaving analogously to light quanta.

常，分子随机热运动，会让声波行为和光量子有别。

2.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.

产生声波岩层和含油岩层、含水岩层或含气岩层之间界面上反射。
