| 摘 要： | 根据分形几何的周长-面积公式及线性回归原理，对TATB等六种炸药样品的落锤试验的分幅图像进行了图像处理和分形维数计算。从中发现，越钝感的炸药样品，分形维数越大。因此，可以认为，用炸药样品的分形维数来鉴别撞击感度是基本可行的。

| Abstract: | The framing photographs of explosive samples under drop hammer test exhibit a fractal structure, in which the fractal dimension is related to the explosive's impact sensitivity. Based on the perimeter-area relation in fractal geometry and the linear recurrent analysis, fractal dimension calculations have been done for six kinds of explosive samples (e.g. TATB). We find that the fractal dimensions of the inert explosives are greater than that of the others. Besides, the sequential orders of the fractal dimension for the six kinds of explosives are in agreement with that of the drop hammer height. Therefore, we consider that it is possible and feasible to characterize the impact sensitivity of explosive with its fractal dimension. |
