Using the method of exercising the medial collateral ligament and extirpating the medial meniscus , an animal model of early osteoarthritis ( oa ) is produced to study the changes of cartilage degeneration and the pathogenesis of early oa . 5 to 10 days after operation , under scanning electron microscope ( sem ) , articular cartilage surface showed collagen fibers network was intact 运用切断内侧副韧带及切除内侧半月板的方法，制作兔早期骨关节病动物模型，研究早期骨关节病的病理变化以及探讨早期骨关节病的发病机制。
Then by using aluminosilicate electrorheological fluid on the modeling device , experiments were carried out to uncover the variations of transmitting properties of four kinds of barriers surfaces with strips at inner surface , outer surface , neither and both surfaces under the same conditions , only to show that barriers surface with strips at both surfaces showed the best transmitting property on the erc 在此基础上，以硅油-硅酸铝流体为er材料，通过实验重点探讨了四种不同界面形式下er离合器输出性能变化及其机理，表明内、外均加直条界面形式下er离合器输出性能较佳，且分析认为实验条件下内筒表面传输效率提高是引起er离合器传输性能增强的主要原因。
Sem micrographs of fracture surface showed that the function of rubber reclaiming agents to increase mechanical properties of composites was mainly counted on changing crosslink density of grt and the compatibilizer on improving interface between wpp / grt / wsf . the results showed that practical applied prospects were provided with wpp / grt / wsf composites by two - screw extruder 冲击断面sem表明，增容剂特别是双组分增容剂的加入，能明显增强wpp基体与grt分散相的相容性，明显改善了二者的界面粘合；再生体系的加入，可使grt分散相的粒度明显减小，起到了降低橡胶交联密度的作用，使胶粉更易分散均匀。
