摘　　要：对不同形状晶核的DLA分形生长进行模拟和比较。结果表明 :不同形状的晶核所产生的DLA图形维数相近 ,晶核的各向异性对分形图形填充空间的能力影响不大 ,不是图形各向异性的主要产生原因。DLA fractal growth of different kernels has been simulated by using computer. The result shows that the dimensions of DLA figures are similar, and the anisotropy of kernels has little effect on fractal figure's filling ability, it is not the main reason for the anisotropy of fractal figure.

关 键 词：DLA 分形 分维 各向异性
