| 1)Supercooling degree significantly affects the crack propagation,which is faster and crack branching is more while the supercooling degree is smaller. |

The smaller the supercooling degree is (that is to say, the higher the temperature is), the faster the crack propagation is and the more crack branching is. 2£©ÁÑÎÆÔÚÀ©Õ¹¹ý³ÌÖУ¬ÌåϵÄÜÁ¦²»¶Ï½µµÍ£¬µ±ÁÑÎÆ³öÏÖ·Ö²æÊ±£¬ÌåϵÄÜÁ¿½µµÍµÄ¸ü¿ì¡£ The results showed that the system energy continously decreased in the process of cracks propagation. The system energy decreased much faster when the cracks started to branch off. Hope it helps you!!!! Good Luck. |
