中文摘要：

本文采用两种方法对钙基脱硫剂孔隙分布特性进行了模拟,结果证明孔长度分布满足对数正态分布的假设和满足同一分布的假设相比与实验结果更加吻合,反映出了孔隙分布的变化特性。

英文摘要：

Two mathematical models were suggested to describe the pore distribution properties of calcium sorbents in this paper. The distribution functions of pore length were satisfied to loga-rithm normally distribution and same distribution respectively. The former hypothesis conforms to experimental results better than later modei, so the pore distribution properties were presented.
