protective layer

基本解释

Based on this case, through filling the gob area by means of chamber blasting, the requirement of protective top - layer for slicing and caving can be achieved.
针对这一情况，从药室爆破放顶充填采空区，从而达到分层崩落法采矿的护顶层要求。
And the protection scopes of steep inclined upper-protective layer of POM located by the method of practical test and numerical simulation are basically consistent.
同时，由现场考察方法与数值模拟方法所确定的急倾斜俯伪斜上保护层保护范围基本一致。

The conclusion can be drawn that it is feasible to study the protection scope of steep inclined upper-protective layer of POM by using numerical simulation and its results are acceptable.
因此，采用数值模拟方法来研究急倾斜俯伪斜上保护层的保护范围是可行的，且结果偏于安全。

The magic, it turns out, is in that subatomic spray, as the group treated with an electron shower benefited from a polymerizing effect or, more plainly, a bonding of molecules just above the skin's surface that yielded a tough, protective nano-layer measuring between 50- to 100-billionths of a meter thick.
ENGADGET
There's even a protective layer of splash-guard coating.

The brushed metal case with protective layer provides 9H scratch resistance, which prevents damage even after long-term use.
ENGADGET: ADATA's got an 8.9mm thick portable USB 3.0 drive, limbos under the competition by .1 of a millimeter

介质保护膜
Luminance and luminous efficacy were measured. Both of the results show that protective layer of MgO film with MgO powder had better performance than traditional MgO film.
实验结果表明,用丝网印刷涂覆MgO粉末方法制备的介质保护膜对AC PDP的光效和亮度都有提高。
