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 DL A模型 .据改进的 DL A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 .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.
