The results showed that for the same material and the same iodine concentration, the rate of crack propagation increased with increasing temperature.
结果表明：对于同种材料在相同的碘浓度下，随着温度的升高，裂纹的扩展速率加快。

The results have shown that the incubation period of crack nucleation decreases and the propagation rate of crack increases with increasing the cyclic temperature.
试验结果表明，随着循环温度的增高，裂纹形核孕育期缩短， 裂纹扩展速率增大；
3
The effects of temperature and stress on the initiation and propagation of cracks are investigated.
