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;
煤吸附氣體動(dòng)力學(xué)過程包括滲流階段、表面擴(kuò)散階段、體擴(kuò)散階段和吸著階段；
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(duì)T1和T2都有貢獻(xiàn)，表面馳豫和體積馳豫對(duì)T1和T2有貢獻(xiàn)，表面馳豫、體積馳豫和擴(kuò)散馳豫對(duì)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)氣體和炭的容積擴(kuò)散本質(zhì)。
