The gas diffusion through the inter-particle and the product layer was the mainly factor on the reaction rate.

一定温度下的速率先增加后减少最后趋于平缓．这是由气相在吸收剂颗粒间的扩散和在产物层内的扩散引起的。

The calcium utility obtained rapid increase in the initial stage and became tardily after the formation of the product layer.

在最初的几分钟内，钙转化率增加迅速，产物层形成后基本不再增加。

The experimental data were fitted to a mathematical model of joint controlled by the chemical reaction at the interface and diffusion of steam through the product layer.

实验数据与界面化学反应和固体产物层内扩散共同控制数学模型相吻合。
