结论AD C值变化与神经、胶质细胞水肿、凋亡及由此产生的水分子无序运动有关。

Conclusion ADC changes are correlated with neurons and glial cells swollen, apoptosis and the out of order motion of water molecules.

在无序区域，水分子之间更为紧密，使他们的密度比以四面体结构排列的区域高。

Inthe disordered regions, water molecules are more closely packed, makingthem denser than regions where the molecules are arranged in atetrahedral structure.

换句话说，事实上你并不真的需要分子，处在格子的位置但存在着无序。

In other words, the fact that you don't really have the molecules sitting in sites on a lattice but there's disorder.

youdao

That is, how many different possible configurations of all those molecules there would be for a particular state.

这里的无序程度表示在一个宏观状态下,微观的分子到底具有多少微观状态。

Higher entropy basically because you're forming molecules of gas where there weren't any before, and there's more disorder in the gas phase than in the liquid. That is, the gas phase molecules have more freedom to roam.

高的熵是因为,我们产生了以前不存在的气体分子,气体的无序程度比液体大，换句话说,气相的分子，有更多的到处游荡的自由度。
