乙烯化学吸附生成的烷氧化合物与物理吸附的乙烯分子发生二聚反应生成新的C-C键同时生成新的烷氧化合物。

From the experiment discovered for the first time the dimethyl ether may substitute CO to take the chain-carrying agent of the peroxy free radical chemistry amplifier system, and optimized the CH_3OCH_3-NO-HO_2 chemistry amplifying system determination condition, the CH_3OCH_3 best density is 1.876 ppmv, the NO best density is 1.3ppmv, and obtained this method chain length CL=124, 5 parallel determinations densities of HO_2 are the 44.0pptv, the relatively standard deviation is smaller than 4%; Although chemistry box model computed result indicated the dimethyl ether, the ethene, the propene and the ethanol all can take the chain-carrying agent of the peroxy free radical chemistry amplifier system, and their simulation chain length all grows up compared to the CO-NO-HO_2 chemistry amplifying systems, but experiments proved the ethene, the propene and the ethanol have not suit the chain-carrying agents.

首次从实验上发现二甲醚可以替代CO作为过氧自由基化学放大系统的链传递试剂，并优化了CH_3OCH_3-NO-HO_2化学放大系统的测定条件，CH_3OCH_3的最佳浓度是1876ppmv，NO的最佳浓度为1.3ppmv，并得到了这一方法的链反应长度(CL=124)，5次平行测定浓度为44.0pptv的HO_2自由基，相对标准偏差＜4％；虽然化学盒子模式计算结果表明二甲醚、乙烯、丙烯和乙醇都能作为过氧自由基化学放大系统的链传递试剂，并且它们的模拟链长都比CO-NO-HO_2化学放大体系的链长大，但是实验证明乙烯、丙烯和乙醇不适合作为过氧自由基化学放大系统的链传递试剂。
