| 中文摘要: |
| 模拟火灾现场,制作不同线径铜导线的火烧熔珠,然后在不同温度下对熔珠进行冷却。利用金相显微镜对火烧熔珠的金相组织进行观察,发现铜导线火烧熔痕在不同温度下经消防射水冷却后,会出现类似一次短路和二次短路熔痕的金相组织。 |
| 英文摘要: |
| Simulating fire scene,melted marks of copper wires with different diameters caused by fire were made and cooled by water.The metallographic structure of melted mark was observed and metallographic structure with secondary short circuited melted mark and primary short circuited melted mark was found. |
