Effects of microwave power, reaction time, reaction temperature, solvent etc. on reaction were studied by a single factor tests. The results show that maleic acid is more active than fumaric acid; the introduction of methyl group on the double bond can weak the reactivity of the Michael addition reaction; the ester base is more propitious to complete the Michael addition reaction than the nitrile base.

为研究微波下迈克尔反应的规律，本文采用单模聚焦微波有机合成仪，通过对顺丁烯二酸、反丁烯二酸和氨水合成DL-天冬氨酸、顺式3-甲基丁烯二酸和氨水合成3-甲基天冬氨酸、丙烯酸甲酯和氨水合成β-丙氨酸、丙烯腈和氨水合成β-氨基丙腈等五个反应对迈克尔加成反应进行了研究。

Results show that ammonia emission occurred within the first 6 days after fertilizer application, and it was less after the basal dressing and the first top-dressing than after the second top-dressing-N loss through ammonia emission accounted for 0.4%~12% of the total nitrogen applied for the basal and the first top dressings. However for the second top-dressing the percentage was 5.8%, 9.7%, 25.6%, 15.6%, 11.6% during the 2002 rice season, and 27.4%, 26.2%, 30.0%, 35.1%, 27.6% during the 2003 rice season for Treatments LN, OPT, LP, HP and HN, respectively.

结果表明，稻田氨挥发损失主要发生在施肥后6d内，基肥和第一次追肥后各处理氨挥发量占施氮量的0.4%~11.5%，而第二次追肥后氨挥发损失比例较大，对照、低氮、优化、低磷、高磷和高氮处理的氨挥发在2002年稻季分别占施氮量的5.8%、9.7%、25.6%、15.6%和11.6%，在2003年稻季则分别为27.4%、26.2%、30.0%、35.1%和27.6%。
