water-proof layer

Chemicals form a protective layer that resists both oil and water-based stains.

化学物质形成了一个抗油污和水渍的保护层。

Using GAB model to calculate the value of the single layer water content is higher than the value calculated by the BET.

利用GAB模型计算出的单层含水量的值高于由BET计算出的值。

The features of overburden strata movement are thick strata, multi-stages, slow development, synchronously collapse of multi-rock, leading a big abscission layer space, which is easy to connect to pre-existing fracture, forming ultra-high guide water flowing fractured zone.

覆岩运动为厚岩层，多阶段、慢发展，多岩层的同步垮落，导致离层空间大，容易沟通原生裂隙，形成超高导水裂隙带。

For the aged or sensitive skin you may spread a layer of essence cream firstly, and spray water to moisten.

如皮肤太过老化或敏感的可先用精华霜打底，并于敷泥过程中适量喷水，保持湿润。

The paper thought it over that swift flow theory and boundary layer theory are the core problems of water treatment mass transfer-reaction kinetics.

研究认为，湍流理论和边界层理论是水处理工艺传质－反应过程动力学的重要核心问题。
