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。

The results of the study could also be applied in the loading of catalyst onto the ion-exchange resin, which could be applied in the organic synthesize.

并利用本课题研究的理论和实验成果应用于杂多酸催化剂的离子交换负载，进而研制出离子交换树脂负载杂多酸催化剂以应用于有机合成。
