rate-controlling step中文什么意思
例句與用法
- Combining quantum chemistry calculation with experimental evaluation , the activation energies of possible interfacial reaction were calculated . it is shown that the first step in which the atomic ti , c and si were decomposed from ti matrices and fiber , respectively , is a rate - controlling step because the activation energy of the step is larger than second one
量子化學(xué)計(jì)算與經(jīng)驗(yàn)估算相結(jié)合，求出了可能發(fā)生的界面反應(yīng)的活化能，表明第一步驟的活化能遠(yuǎn)大于第二步驟的活化能，因而第一步驟是反應(yīng)的動(dòng)力學(xué)控制因素，在這一步驟中，原子態(tài)的ti 、 si 、 c分別從基體鈦合金和纖維中分解出來(lái)。
