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。
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.
被融化的岩石由于粘性较低，因此能轻易流到岩石层上方形成火山锥。
The melted rock has a low viscosity, and it flows easily up through the overlying rock.
为了反映冲击载荷下岩石材料的应变率敏感性，对损伤的门槛值进行粘性调整。
The damage threshold is regularized in order to reflect strain-rate sensitivity of rock materials under impact load.
