They were both easily to be dissolved in dilute alkali. When the pH gradually increases, the ring-opening speed of the derivative is higher than that of GB. The derivative was obviously affected by solvent and higher temperatures. When GB was dissolved in PEG, the peak of the derivative disappeared at 50 ℃ for 15 h or at 120 ℃ for 4 h. Besides the main peak of GB, there appeared a small peak with a retention time of 1.2-3.0 min after heating 4 h at 120 ℃. The result showed that the derivative was in a high energy state, and GB had a better stabilization.
溶剂和温度的综合作用对衍生物的稳定性影响更加显著,GB在聚乙二醇溶液中分别于50 ℃下保存15 h和120 ℃下保存4 h后其中的衍生物峰全部消失;将该溶液于120 ℃下保存4 h后分析,除有主峰GB外,在保留时间为1.2~3.0 min范围还伴随有小峰出现,这说明衍生物处于高能态,GB相对较为稳定,两者共存,且相互转化;在特定条件下衍生物能全部转化为GB。

In this paper, a scale space clustering algorithm based on mathematical morphology operators is proposed. The data are firstly converted into a binary image, the noises are then deleted with close open operators. A scale space is constructed with the close operator and structure elements as well as increased size. The connected cells merge with each other with the increasing scale until all of them combine into one.
