In this paper, active groups terminated silicane was used to react with the hydroxyls of bisphenol A epoxy resins, that introduced organic silicon without consuming epoxy groups. This modifying process improved the combining degree of the cured resin, so both the toughness and the other characters (as strength, thermal resistance) were all could be improved.

为此本论文采用国内外文献中尚未见报道的、带活性基团的有机硅来改性双酚A型环氧树脂，通过端基基团与环氧链上的羟基反应生成大键能的Si-O键的方式来引进有机硅，改性过程中不仅不消耗环氧基，并且还提高了树脂固化物的交联密度，所以既能增韧树脂，又能提高其耐热、耐冲击等各项性能。

RESULTS: During 10 - 12 weeks, in cuntrol group: The defect area was repaired by white and soft tissue that had no resistance to press. The repaired tissue was still lower than the surrounding articular surface with clear boundary. By histological observation, it was found that the defect was repaired by the mechanism similar to inflammatory reaction and the defect is ultimately filled by the hyperplasia of hyaline degenerative fibrous tissues. In filling group: the defect was repaired by semi-transparent, smooth, textured tissues with polish that had resistance to press as well as elasticity. The repaired tissue was almost similar to the shape of the surrounding cartilage,difficult to be distinguished. After histological observation, it was found that there was no inflammatory reaction, but active hyperplasia of inner bonetissue and cartilage tissues; a lot of osteoid tissues and trabeculation were found. Newlborn cartilage was fused with surrounding cartilage tissue and connected with surrounding tissues.

结果：10～12周，对照组：缺损区由白色、质软、按压无阻抗的组织修复，修复组织仍低于周围关节面，边界仍清晰可辨，组织学以类似炎症反应的机制修复缺损，最终以透明变性的纤维组织的增生来填补缺损部位；填充组：缺损区由半透明状、质韧光滑有光泽，按压有阻抗并有弹性的组织修复，修复组织与周围软骨外形上已基本相似，不易区分，组织学未见有炎症反应的过程，内骨组织和软骨组织增生活跃，并可见大量类骨组织和骨小梁形成，新生软骨和周围软骨组织融合，并与周围组织连接。
