The propagationrateofcrack also decreases with increasing the binder content of cermets.
随着金属陶瓷中金属相含量的增加，裂纹扩展速率降低。
2
The metastable propagationrateofcrack is approximately a constant in a certain size range.
在一定尺寸范围内，裂纹的亚稳扩展速率近似是常数。
3
The results have shown that the incubation period ofcrack nucleation decreases and the propagationrateofcrack increases with increasing the cyclic temperature.
