Results show that chemical reaction between additives Al2O3 and Y2O3 accelerated the liquid phase sintering and the formation of the YAG non-crystalline,which was beneficial to improving fracture toughness of Cf/SiC composites.Higher sintering temperature resulted in the strongly bonded fiber/matrix interface.Fiber push-off,crack deflection and grains bridging are main toughening mechanisms of silicon carbide cera...

结果表明：烧结过程中，烧结助剂Al2O3、Y2O3之间发生化学反应，促进液相烧结，形成晶界间的次晶相YAG(3 Y2O3.5Al2O3)，有利于提高复合材料的断裂韧性；在较高烧结温度下，碳纤维、烧结助剂与基体间发生反应，形成较强结合界面；纤维拔出、裂纹偏转和晶粒桥联是碳化硅陶瓷的主要增韧机制。

Furthermore,this change in molecular conformation from one stable state to another induced by torsion angle can be expected to cause a conductance switching in the system.

这些结果说明了4，4\'-二巯基联苯分子在分子尺度上的逻辑元件方面存在着潜在的应用价值。
