英文摘要：
To analyze the effect of pore fractal dimension and fractal structures on the particle diffusion characteristics,a fractal structure is built and the particle random walk in it is simulated,and the movement mechanism of particle diffusion in fractal media is explored. The numerical simulation results show that the particle diffusion behavior in fractal structure is affected by the factors,such as the start position,the shapes of main channel and sub-channel,the fractal dimension,etc.
