hydration

The team believes one of the most important factors is hydration - the way skin collects and retains moisture..科研人员称，其中最重要的因素是水合，指皮肤吸收水分、保持湿度的过程。

Previous experiments and simulations, however, indicated that the free energy of hydration did not match this predicted linear trend..然而，过去的研究和模拟表明，烷烃的水化自由能并不符合预计的线性变化趋势。
