| 中文摘要 |
| 准确判断臭氧（O3）生成敏感性对O3污染成因分析和防控对策的制定至关重要.首次利用响应曲面方法设计最优试验方案，基于盒子模式模拟结果，快速量化O3对其前体物变化的响应.结果表明，CO对O3有正贡献，NOx和VOCs与O3呈现显著非线性关系，当φ（VOCs）与［φ（NOx）-13.75］比值大于4.17时，为NOx控制区，小于4.17时，为VOCs控制区；烯烃为影响O3生成的关键VOCs组分，当φ（烯烃）与［φ（NOx）-15］比值小于1.10且φ（烯烃）<35×10-9时，烯烃有利于O3的生成.响应曲面法在多因素和其交互作用对O3生成影响的研究中取得了良好效果，为高效判断O3敏感性提供了新的思路和方法. |
| 英文摘要 |
| Identifying the nonlinear relationship between O3 and its precursors accurately plays an important role for the policy-making of O3 pollution control. In this study, the response surface methodology based on the box model simulation was used to quickly and efficiently quantify the O3 response to their precursors with the optimal experimental design. The results showed that CO had a positive contribution to ozone generation, whereas NOx and VOCs had a significant nonlinear relationship with O3. When the ratio of φ(VOCs) to[φ(NOx)-13.75] was greater than 4.17, the ozone formation regime was NOx-limited and became VOCs-limited when the ratio was less than 4.17. Olefin was the key VOCs' component to affect the formation of O3; when the radio of φ(olefin) to[φ(NOx)-15] was less than 1.10 and the value of the φ(olefin) was less than 35×10-9, olefin went far towards generating O3. Response surface methodology demonstrated that it can be well used to explore the influence of multiple factors and their interactions on O3 formation and provides a new approach for efficient O3 sensitivity analysis. |
