| 摘 要： | 在室温和1.01×105 Pa条件下,利用烟雾箱以及气相色谱和臭氧分析仪研究手段,采用绝对方法(准一级反应)获得了臭氧与二甲硫醚(DMS)和乙烯(C2H4)的反应速率常数,分别为:kDMS=(1.48±0.12)×10-20 cm3·molecule-1·s-1;kC2H4=(1.35±0.10)×10-18cm3·molecule-1·s-1.其中,臭氧与乙烯的反应速率常数与文献报道吻合较好,臭氧与DMS的反应速率常数比文献报道的上限值低约两个数量级. |

| Abstract: | Rate constants of the reactions of ozone with dimethyl sulfide (DMS) and ethane (C2H4) were measured at room temperature and 1.01×105Pa. Measurements were carried out in a smog chamber by using absolute method ( pseudo-first order reaction). The rate constants are KDMS=(1.48±0.12)×10-20 cm3·molecule-1·s-1and kC2H4=(1.35±0.10)×10-18 cm3·molecule-1·s-1. The value of ethane rate constant is in good agreement with that of others reported. The value of DMSconstant is about two orders of magnitude lower than that of other reported. |
