| 在不考虑和考虑A和B所参与反应这两种条件下，分别得到了C随停留时间的演变规律。结果表明：当考虑A和B所参与的反应时，模拟结果与实际更为相符；D过程中会明显产生E、F、G，说明H的脱除有还原与氧化两种途径；当气体停留时间达到接近2.5s时，E和F被完全脱除，P浓度约为5×10-6；在2.5s到3s之间的时间段内，还存在少量的J和K，但到3s时，二者浓度已基本趋于平衡，此时P浓度约为3.2×10-6；M、N原子的浓度呈脉冲变化，但两者的变化不尽相同，N原子的浓度快速上升，达到了10-6量级。 |

在不考虑和考虑A和B所参与反应这两种条件下，分别得到了C随停留时间的演变规律。结果表明：当考虑A和B所参与的反应时，模拟结果与实际更为相符；D过程中会明显产生E、F、G，说明H的脱除有还原与氧化两种途径；当气体停留时间达到接近2.5s时，E和F被完全脱除，P浓度约为5×10-6；在2.5s到3s之间的时间段内，还存在少量的J和K，但到3s时，二者浓度已基本趋于平衡，此时P浓度约为3.2×10-6；M、N原子的浓度呈脉冲变化，但两者的变化不尽相同，N原子的浓度快速上升，达到了10-6量级。 Considered two situations that A and B were involved in reaction and neglected the two participants, evolution regulations of C as residence time goes were obtained, respectively. The results showed that when considering A and B, simulation results are accord with actual case. Obviously, E, F, G were produced in D process. It indicates that two ways, reduction and oxidation, were included in the removal of H. When gas residence time reached close to 2.5s, E and F were completely removed, and concentration of P was about 5×10-6. During the period between 2.5s and 3s, there was a small amount of J and K. But at 3s, concentrations of both of them showed basically balance. Here P concentration was about 3.2×10-6, while M, N atom concentration changes in pulse. However, there were differences between the changes for them that N atomic concentration performed a rapid increase in 10-6 level. |
