| 摘 要： | 完善了王革丽和杨培才(2007)建立的平流层下部臭氧异相光化学反应箱式模式,在原有模式基础上加入溴族,研究了平流层下部臭氧对硫酸气溶胶表面积浓度与氯化物、溴化物以及氮氧化物的排放强度变化的非线性响应,理解平流层臭氧对人类活动的依赖性.结果表明,当氯化物排放强度偏离当前水平时,气溶胶可以通过与溴化物、氯化物、氮氧化物之间的相互作用,干预光化系统的非线性行为,改变系统在参数空间中的拓扑结构. |

| Abstract: | Bromide was considered to improve the box-model of lower stratospheric ozone heterogeneous photochemical reactions established by Wang and Yang (2007). To obtain further understand of the relationship of stratospheric ozone levels and human activities, the authors investigate the nonlinear response of the lower stratospheric ozone toward the changes in emission intensity of sulfuric acid aerosol, chloride, oxynitride, and bromide. On the basis of the analysis, the authors conclude that when the chloride emission intensity deviates from standard levels, the mutual interaction between aerosol and chloride, oxynitride, and bromide can affect the photochemical system nonlinear response and change the topological structure of parameter space. |
| Keywords: | stratospheric ozone heterogeneous chemistry mutation periodic solution |
