| 摘 要： | 用电化学沉积方法，在负电极周围生长出二维铅枝晶，通过处理其表面形貌，计算了铅枝晶的分形维数．修改了DLA模型．据改进的DLA模型，用计算机模拟了铅枝晶生长图像．结果表明，铅枝晶明显具有分形的自相似特征．对影响铅枝晶结构的因素进行了讨论．

| Abstract: | The two\|dimensional dendrite of lead metal was grown on an electrode of carbon by the electrodeposition method. The dimension of the dendrite of lead metal was calculated by using its graph. The growth model was calculated by computer, which proved that the dendrite of lead metal has the character of self\|similar of a fractal. The factors on influencing structure of the dendrite of the lead are discussed. |

| Keywords: | electrodeposition dendrite of lead fractal dimension of fractal |
