摘　　要：将一种改进的目标因子分析法（ＭＴＦＡ）用于复杂反应的速差动力学分析体系，采用此法处理实验数据时，引入了一个非零截距因子，采用模拟纯谱运算。可使方法的准确度大大提高。据此建立了一种停流技术进样、速差动力学分析同时测定、因子分析处理实验数据的新方法；对于１０￣（－６）ｍｏｌ·Ｌ￣（－１）级的肾上腺素－去甲基肾上腺素混合物，比例范围在１：５～５：１之间，测定相对误差小于±１０％，用于合成样品中肾上腺素和去甲基肾上腺素的同时测定，获得了满意结果．A modified target factor analysis(MTFA)method has been applied to differential rate kinetic system in which synergic effects are taken into account in this paper.A simple differential kinetic method by stopped-flow and MTFA has been proposed.In the meantime,the optimum experiment conditions of oxidation of EP and NE with Fe(phen)were investigeted. This mehtod has been applied to the determination of two component EP and NE with satisfactory results. The accuracy the of method was greatly improved.
