| 摘 要： | 以动态生成的CaO孔隙网络为骨架，按照不退行随机行走模型（NRRW），模拟气体分子在CaO孔隙中的扩散过程，计算了SO2分子的扩散系数和行走维数，并在SO2非线性扩散反应方程基础上，分析了CaO颗粒孔隙中SO2浓度的分布特性。

| Abstract: | The processes of SO, diffusion in CaO samples were simulated with the Not - Reversal - Random Walk （NRRW） model and pore networks produced by the above - mentioned pore network formation model which were used as the space frameworks of molecule motion. The gas concentration distributions in the pore networks were studied. SO, diffusion characteristics in a fractal pore were analyzed. |
