surface diffusion rate的意思|示意

Adsorption of sucrose on activated carbon is a chemical adsorption process and belongs to mono-molecular surface adsorption. The adsorption rate is controlled by internal diffusion.

活性炭吸附蔗糖是一种化学吸附过程，蔗糖是以单分子铺展的形式被吸附于活性炭表面，其吸附速率由内扩散所控制。

The gasification reaction rate would reduce because ash would melt, which will plug the coal surface pores and increase gas diffusion resistance.

高温下煤灰发生熔融，将会堵塞煤焦表面孔隙，增大气体扩散阻力，降低气化反应速率。
