中文摘要：

O3是对流层大气中一种重要的氧化剂,其与反应活性气体的反应是大气对流层中重要的反应过程,对于研究空气污染的对策有重要意义.我们使用自行建设的烟雾箱模拟反应装置,结合O3分析仪和气相色谱研究了O3和乙炔的反应.研究测得O3和乙炔在室温下(15℃)反应的4次实验的速率常数的平均值为4.13×10-21cm3?molecule-1?s-1,其变动系数为7%.与文献中采用其它方法得到的实验值相吻合.所得结果表明,我们测定的反应速率常数有较高的精密度,我们所建的大气反应烟雾箱模拟系统是可靠的,可以用于大气O3浓度条件下O3的其它大气化学反应过程的深入研究,为进一步深入研究大气中其它重要反应活性气体的化学反应提供了一定的基础.

英文摘要：

Ozone is an important oxidant in the troposphere, and its reactions with reactive gases are im- portant processes in the troposphere, which has a significance for the research on countermeasures of air pollution. The simulative reaction equipment of smog chamber, made in our laboratory, was used to study ozone reactions with acetylene in terms of monitoring instruments of ozone analyzer and gas chromatogra- phy. A mean value of 4.13×10-21 cm3?molecule-1?s-1 for rate constant was obtained from four experimen...
