摘　　要：利用180-L Teflon气袋,采用相对速率方法测定了298K,1.013×105 Pa条件下·OH自由基与6种还原态硫化物在空气、氮气和氧气体系下的反应速率常数.所得结果与文献值进行了比较,并讨论了氧气对速率常数的影响.The rate constants for the reactions between · OH and six reduced sulfur compounds in air, N2, and O2 were measured using relative rate constant method in a 180-L Teflon bag at 298 K and 1.013×10^5 Pa. These results were compared with previous published data and were discussed in terms of trends in different buffer gases.
