Existence and linear stability of planar waves in the Oregonator model

In this paper,various waves in the Oregonator model are investigated in detail.The existence of planar waves(in particular,spiral waves)is rigorously proven and their linear stability is analysed.In addition,some non-planar waves in the model are also presented.     

新型2-甲基吲哚衍生物的合成

2-甲基吲哚在草酰氯的存在下与DMF或DMA通过Vilsmeier-Haack反应制得2-甲基-3-甲酰基吲哚(1)或2-甲基-3-乙酰基吲哚(2);1或2与烷基化试剂通过N-烷基化反应合成了一系列新型的2-甲基吲哚类衍生物,其结构经1HNMR,13C NMR,IR和MS表征。
