From experiments the results are followed: 1 While selecting the mixed resin liquid, Conversion Loading decide the performance of the resin liquid.

由试验结果得出如下结论：1在选择混合树脂液时，转化率的大小决定了树脂液的优劣。

For the UPR with greater brittleness, the brittle-tough transition was observed only when the toughness of the resin was characterized by fracture toughness at a slower loading rate.

对于脆性较大的UPR，只有在采用加载速度较慢的断裂韧性来表征其韧性时，方能观察到这一脆韧转变现象。

The results indicated, when compared to the pure epoxy resin, that the mechanical and thermal properties of the nanocomposite could be greatly improved by addition of low clay loading.

结果表明，少量蒙脱土的加入可以较大地提高材料的力学性能和耐热性能，对环氧树脂同时起到了增韧增强的作用。
