Clean the skin, the skin surface because the natural sebum film has completely disappeared, this state if frequent persistent, rough skin and lead to aging, so wash your face after the use of a humidor and the convergence of the neutral makeup water, care An indispensable part of the skin, particularly in older women, reduced ability to skin secretion, this session is even more important.

清洁皮肤之后，由于皮肤表面自然的皮脂膜已经完全消失，这种状态如果频繁持续存在，会导致皮肤粗糙和老化，因此，洗脸后使用具有保湿和收敛作用的中性化妆水，是护理皮肤必不可少的一个环节，特别是中老年女性，皮肤分泌能力下降，这个环节更加重要。

Test results of EMP-steel frictional pairs showed that the wear rate h of EMP, press p andvelocity v are suited to equations separately: h =m .p n and h =a .v b.

试验证明EMP复合材料瓦与钢对磨时的磨损率h与压力p、速度v之间分别满足h=m.pn和h=a.vb关系式，给出了相应系数m、n、a、b的值；磨损率与钢试件表面粗糙度Ra之间满足h=A·RaB关系式，给出了A、B的有效范围值。
