Relieved of the overlying pressure, the volcano ejected a blast of rocks, ash, gas, and steam that blew down and buried several hundred square miles of forest.

随着顶部压力的解除，火山激烈喷涌出大股的岩石、灰尘、气体和蒸气，降落下来后覆盖了数百平方英里范围内的森林。

Systematic physio-mechanical properties test and analysis, especially analysis of relationship between expansion rate, dry density, water content, and overlying pressure, are carried out.

本项工作系统地进行了膨胀土的物理-力学性质试验及分析，尤其是膨胀率与干容重和含水量及外覆压力关系分析。

Although the hot rock of the mantle is a solid, under the tremendous pressure of the crust and overlying rock of the mantle, it flows like a viscous liquid.

虽然地幔的热岩石是固体，但在地壳和地幔上覆岩石的巨大压力下，它像粘性液体一样流动。
