L-system and IFS are used to the plant s simulation. In this package the theories of L-system and IFS were concisely described. The excellence and short of constructing Fractal image with L-system or IFS were discussed. So a method was put forward in

基于分形理论的WZ模型的圆板绝缘系统击穿时电树枝现象的计算机模拟。-The simulaton of electrical tree growth based on fractal theory and WZ model.
