The effective diffusion coefficient and rate constant of intraparticle transport were calculated. 求出了顆粒內有效擴散系數和顆粒內擴散速率常數。
The knowledge of diffusion is crucial in many processes because reactions and separations are often limited by a diffusional process. 摘要許多過(guò)程都涉及擴散控制的傳質(zhì)，相應的擴散速率計算對過(guò)程工程的精確量化具有重要意義。
In some sense, it is the synchrony that induces diffusion slowing. 這種同步狀態(tài)正是擴散速度下降的原因。
Nevertheless, temperature has a very significant effect on the rate of diffusion. 但是溫度對擴散速度卻有非常大的影響。
