The basic characteristics of gas convectivediffusion of underground coal gasification (UCG) are studied.
气化气体对流扩散的基本特征。

Based on the diffusion layer, variation and convectivediffusion, 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。

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