| 摘 要： | 利用火灾痕迹物证综合实验台，制备铝导线在不同过载电流作用下的残留物，用扫描电子显微镜观察、分析导线的断口形貌.结果表明:随着过载电流的增大，杯锥状断口逐渐变大，杯锥底部韧窝越来越大.因此，利用扫描电子显微镜观察、分析铝导线的断口形貌特征，可以鉴别其是否过载以及过载的程度.

| Abstract: | The integrated experimental system of material evidence for fire trace was used to make residues of aluminum wire under different overcurrents.The fracture morphology of the wire was observed and analyzed by the scanning electron microscopy.The results show that with the increase of overcurrent the cup-cone fracture becomes larger,and the the dimple also becomes larger.Therefore,scanning electron microscopy can be used to observe and analyze the character of the fracture morphology of aluminum wire and iden... |
