结合橡胶和增强作用的研究表明，在混炼胶中，硅橡胶与矿物填料的作用形式有四种。没有联结在矿物表面的非结合橡胶和仅靠物理吸附联结在填料表面的硅橡胶将溶解于有机溶剂；与填料有较强相互作用的硅橡胶不溶于有机溶剂；通过不同层次的酸碱作用联接在矿物表面的硅橡胶将溶解于碱性有机溶剂；与填料有牢固化学结合的硅橡胶不溶于碱性有机溶剂。

At present,the rate laws and reaction mechanisms of pyrite oxidation,pyrite and chalcopyrite formation,uraninite and magnetite dissolution in aqueous solutions are mainly studied,and it is discovered that (1)oxidation rate of pyrite controlled by surface reaction assume fractional dependence on Fe3+ and O2 molalities in acid solutions;(2)Pyrite cannot nucleate directly from solutions below 300 ℃,it can only form initially through sulfidation of a FeS precursor. The rate equation of reaction between FeS and H2S to form pyrite is of the second order;(3)Chalcopyrite is formed by reactions of pyrrhotite or pyrite with Cu2+,the former proceeds via a series of mediate metastable phases of Cu-Fe sulfide,whereas the rate equation of the latter is apparently of the first order which is controlled by surface reaction;(4)The nonlinear behavior of magnetite dissolution at acid pH can be represented by a shrinking core model coupling with surface reaction and diffusion transport.

目前主要研究了水溶液中黄铁矿氧化、黄铁矿和黄铜矿形成、晶质铀矿和磁铁矿溶解的速率定律和反应机理，发现：(1)酸性溶液中黄铁矿的氧化速率对Fe3+和O2浓度呈分数依赖并受表面反应的控制；(2)低于300 ℃时黄铁矿不能从溶液中直接成核，而需初始地通过FeS先驱物的硫化生成，FeS与H2S反应形成黄铁矿的速率方程为二级；(3)磁黄铁矿或黄铁矿与Cu2+反应均可形成黄铜矿，前者经历了一系列准稳的Cu-Fe硫化物的中间物，后者的速率方程为表观一级并受表面反应的控制；(4)酸性pH时磁铁矿的非线性溶解行为可采用表面反应扩散输运耦合的收缩核模型来描述。

The results show that although the profile w ear of the surface is not beneficial to the lubrication, the asperity wear does. In consideration of coupling wear of profile and asperity, the minimum film thi ckness increases in a certain worn height. Therefore, the wear of asperity is be neficial to lubrication in this region.

分析结果表明：在重载条件下表面轮廓磨损不利于润滑，而表面微突体的磨损则有利于润滑；当同时考虑表面轮廓和粗糙度时，在一定磨损高度内，磨损显著增加润滑膜的最小膜厚，从而有利于润滑。
