diffusion resistance

基本解释

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。
It contains nutritious elements and rich water, and has high diffusion resistance in soil of retaining in the applied position reaching the delay-releasing effect.
含有营养元素的富水液体在土壤中的扩散阻力陡增，长时滞留于追施部位，达到了液体肥料缓释的效果。
