diffusion resistance

基本解釋

The gasification reaction rate would reduce because ash would melt, which will plug the coal surface pores and increase gas diffusion resistance.
高溫下煤灰發(fā)生熔融，將會(huì)堵塞煤焦表面孔隙，增大氣體擴(kuò)散阻力，降低氣化反應(yīng)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.
含有營養(yǎng)元素的富水液體在土壤中的擴(kuò)散阻力陡增，長時(shí)滯留于追施部位，達(dá)到了液體肥料緩釋的效果。

This model takes into account both the diffusion resistance of the membrane phase in non-steady state and the diffusion resistance of the external phase boundary film and the membrane leakage.
該模型不僅考慮了非穩(wěn)態(tài)下膜相擴(kuò)散阻力，而且還考慮了外相邊界層的擴(kuò)散阻力及膜破裂。
