第一个反应阶段为速率控制步骤。
第二和第三阶段分别是中孔和微孔扩散过程，颗粒内扩散为速率控制步骤。
The second and third fractions were mesopore and micropore diffusion respectively, and the intraparticle diffusion was the control step.
第二步是缓慢的速率控制步骤，粘结在催化剂上的NO2 +与底物反应。
The second step was slow and rate-determining, catalysis bonded with NO2 + reacted with reactant.
