中文摘要：

有限元素方法被用来解决液体在地球的外壳和披风之间的动态相互作用问题。为了考虑不同机械行为，由外壳组成的岩石圈和上面的披风，作为浸透液体的多孔的岩石被模仿，当披风的上面的 aesthenospheric 部分作为粘滞被模仿时液体。因为整个岩石圈计算地被模仿，在外壳和上面的披风之间的动态相互作用适当地被考虑。特别地，混合披风液体和外壳的液体在相应计算模型被模仿。从一个例子问题的相关计算模拟结果证明披风液体能由于结果与外壳的液体流进外壳和混合在外壳披风系统的对流流动。同样，外壳的液体能也与披风液体流进上面的披风和混合。混合的这种液体和交换对在地球的上面的外壳中控制矿石身体形成和矿化作用的管理进程的更好的理解很重要。

英文摘要：

The finite element method was used to solve fluid dynamic interaction problems between the crust and mantle of the Earth To consider different mechanical behaviours, the lithosphere consisting of the crust and upper mantle was simulated as fluid-saturated porous rocks, while the upper aesthenospheric part of the mantle was simulated as viscous fluids. Since the whole lithosphere was computationally simulated, the dynamic interaction between the crust and the upper mantle was appropriately considered. In particular, the mixing of mantle fluids and crustal fluids was simulated in the corresponding computational model. The related computational simulation results from an example problem demonstrate that the mantle fluids can flow into the crust and mix with the crustal fluids due to the resulting convective flows in the crust-mantle system. Likewise, the crustal fluids can also flow into the upper mantle and mix with the mantle fluids. This kind of fluids mixing and exchange is very important to the better understanding of the governing processes that control the ore body formation and mineralization in the upper crust of the Earth.
