With the increase of pressure, the hydrogen bond strength between water molecules increases, while self-diffusion coefficient decreases. With the increase of temperature, the hydrogen bond strength between water molecules decreases, while self-diffusion coefficient increases.

模拟结果表明，随着压强的增大，水分子间的氢键作用增强，扩散系数减小；随着温度的升高，水分子间的氢键作用减弱，有序程度下降，扩散系数增大。

A semipermeable membrane is one through which the molecules of a solvent can pass but the molecules of most solutes cannot.

半透膜允许溶剂分子通过，而大部分的溶质无法通过。

The contact mode AFM could be used to "sweep" the slipcover and expose the mark. As an example, in situ observation of the bovine serum albumin adsorption film on highly ordered pyrolytic graphite was described. When the marks, atomic steps on HOPG, were covered by BSA molecules, contact mode AFM could "sweep" the BSA molecules away.

以对高序热解石墨（Highly ordered pyrolytic graphite，HOPG）表面牛血清白蛋白（Bovine serum albumin，BSA）吸附的原位观察为例，在BSA膜覆盖HOPG表面的原子台阶后，采用接触模式AFM扫描，将BSA"扫"开，露出HOPG原子台阶作为标记，对图像上的结构进行精确定位。
