| 摘 要： | 本文分析了应用分形维数描述材料断口轮廓形貌几何特征的局限性。结果指出，分形维数对于材料断口粗糙度的变化是不敏感的，该参数与材料断口轮廓几何形态和断裂韧性之间不存在确定性的关系。

| Abstract: | The limitations of the fractional analysis on the characterized fracture profile were studied.The results showed that the fractional dimension, as an indicator of fracture roughness, is insensitive to the fracture surface morphology variation, and there is no physical basis for a correlation between the fractional dimension and fracture mechanisms. |

| Keywords: | fracture profile fractional dimension roughness parameter |
