中文摘要：

假设孔隙分布服从指数形式分布与对数正态形式分布，建立了指数形式模型与对数形式模型，并采用这两个模型分别对CaO孔隙分布特性进行了模拟，结果证明，在一定的孔径范围内，考虑了孔径密度分布的指数形式模型较对数形式模型更与实验结果相吻合，能更好地反映孔隙分布的变化特性，同时提出了在同一模型中，对孔隙长度分布和孔径分布定义成不同形式的设想．

英文摘要：

Supposing that pore distribution of calcium oxide is satisfied to index distribution and logarithm normally distribution, two mathematical models including the index structure model and the logarithm structure model were presented in order to describe the pore distribution properties of calcium oxide in this paper. The results show that the index form model considering pore-size distribution density of sorbents conforms to experimental results better than the logarithm structure modelin some pores size range, and the pore distribution properties were described well. An idea was advanced that different distribution formation were supposed to pores length and pores size in a model.
