Although there are a lot of researches on the seepage flow of underground water, few of them are for soil stone mixture because of its largely increasing scale of FEM solution.

虽然用有限元法分析地下水渗流的工作很多，但对土石混合介质而言，由于有限元法的解题规模迅速增加，其研究甚少。

On the basis of the new study, he thinks that such sequestration may not always happen and probably depends on the composition of sediments and the complexity of water flow underground.

在新研究的基础上，他认为这种隔离并不是经常发生并且还有可能决定于沉积物的构成和地下水流动的复杂性。

The scientists say their best explanation for this is the flow of salty water, possibly underground, although they say the findings don't provide direct evidence of water on Mars.

然而他们表示，该发现并不能提供火星上有水存在的直接证据。

Detailed studies of the surface indicate that these were formed by a lake caused by the flow of underground water that periodically made its way to the bottom of the crater.
