The integral N-S equation is regarded as a special diffusion equation and the pressure term, convective term are regarded as source terms.

将此N S方程看作一个特殊的扩散方程，将压力项与对流项看作是源项，得到一个积分方程。

Based on the diffusion layer, variation and convective diffusion, the models were able to clearly predict the dissolution rates. However, the model for particles needed to be improved.

模型以扩散层概念和变化为基础，加入对流的影响，可清楚地描述溶出数据，但粒子溶出模型需要改进。
