rate-controlling step中文什么意思
例句与用法
- 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
量子化学计算与经验估算相结合，求出了可能发生的界面反应的活化能，表明第一步骤的活化能远大于第二步骤的活化能，因而第一步骤是反应的动力学控制因素，在这一步骤中，原子态的ti 、 si 、 c分别从基体钛合金和纤维中分解出来。
