原子的扩散传质速率是控制总反应速率的关键因素。
The rate of N atom diffusion is the key factor of controlling whole nitridation rate.
这意味着，即使只有一小部分的光生载流子作用于光生甲烷化反应，光化学对总反应速率的贡献也是巨大的。
This means the photochemicalcontribution to the overall reaction rate is significant, even if only a smallportion of photogenerated charge carriers contributes to the photomethanationreaction.
采用这种集总方法可以使总反应速率的计算得到简化，而且可以减少对体系进行描述所需的动力学参数的数目。
The resulting method makes the calculation of the total reaction rate much easier, and provides an effective means of reducing the number of parameters required to adequately describe the system.
