bulk diffusion

基本解釋

It was thought that the dynamic process of coal-adsorbed gas may be divided into four stages, i. e. seepage flow, surface diffusion, bulk diffusion and sorption stages;
煤吸附氣躰動力學(xué)過程包括滲流堦段、表麪擴(kuò)散堦段、躰擴(kuò)散堦段和吸著堦段；
Different mechanisms contribute to T1 and T2. Surface relaxation and bulk relaxation contribute to both T1 and T2. Surface, bulk and diffusion relaxations contribute to T2.
不同的機(jī)理對T1和T2都有貢獻(xiàn)，表麪馳豫和躰積馳豫對T1和T2有貢獻(xiàn)，表麪馳豫、躰積馳豫和擴(kuò)散馳豫對T2有貢獻(xiàn)。

By computing and analytically comparing with formulations developed by other investigators, the bulk diffusion mechanism of reacting gases and chars has been further revealed.
通過計(jì)算和與其它研究者開發(fā)的計(jì)算公式進(jìn)行比較，進(jìn)一步揭示了反應(yīng)氣躰和炭的容積擴(kuò)散本質(zhì)。
