molecular diffusion rate

基本解釋

Water molecular diffusion coefficient increases exponentially with temperature and there is a turning point around 1050℃ after which the increasing rate slows down significantly.
水?dāng)U散系數(shù)隨溫度而指數(shù)增大，在1050℃附近有一轉(zhuǎn)折點(diǎn)，擴(kuò)散系數(shù)增加速率顯著減慢。
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種化學(xué)吸附過(guò)程，蔗糖是以單分子鋪展的形式被吸附于活性炭表面，其吸附速率由內(nèi)擴(kuò)散所控制。
