There are three primary types of wear:(1) abrasie, in which the harder of the surfaces produces grooes in the softer material,(2) adhesie, in which the softer material is transferred as a thin film onto the harder surface, and (3) fatigue, in which repetitie loading produces subsurface cracks and particles, or sheets of material subsequently delaminate and are lost from the surface.

磨损主要有三种类型：1、研磨，硬质表面在软质材料上造成沟槽；2、粘着，软质材料形成薄膜移覆于硬质物体的表面；3、疲劳，反复负载造成材料表面断裂及颗粒形成，或材料出现层裂并从表面脱落。

According to the characteristic of silver nanoparticles, their uniform dispersion in reaction media was obtained by surface modification, ultrasonic radiation and the select of emulsion, and then emulsion polymerization system were formed by combination with reactive monomer and initiator. Nano-Ag/Polystyrene core-shell particles were prepared by emulsion polymerization and their microstructure were characterized by TEM, FTIR, XPS, AFM and TG/DTA. The experimental results showed that silver nanoparticles were coated by polymer and the composite particles had typical core/shell structure, and the microlevel combination was realized. Meantime, the form mechanism of nano-Ag/polystyrene core-shell particles was tentatively researched. The conclusion is that the perfect coating was able to obtained by the control of reaction condition.

产生光油薄膜雾化条件正常情况下，上光油一般不会产生雾化，例如用户在香烟盒表面往往在表面再覆一层聚烯烃薄膜后，湿度大、特别是气温高到一定条件时，当底油涂布后，面油往往因极短暂的气雾致使光油附着牢度不好，而覆在上光油表面的聚烯烃薄膜就会出现浓浓的均匀的雾状小蒸汽，这时反而降低或导致商品的肉质的变化。
