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. 电沉积 铅枝晶 分形 分维 electrodeposition dendrite of lead fractal dimension of fractal 10.14188/j.1671-8836.2000.06.011 O646.5 国家自然科学基金资助项目! （ 5 93 3 10 3 0 ） 2000-06-01 2021-04-01 6
