摘　　要：按照具有参数约束的两组分递次衰变曲线分解的要求,采用非线性规划的直接搜索方法———可变差容法(FLEXIPLEX)求解最优化目标函数。为更有效地求得参数在约束区域内的整体最优解,提出了一具有迭代过程的随机搜索算法。介绍了该算法的特点和计算结果。According to the demands for analyzing two component successive decay curve with constraints in parameter region,a nonlinear programmingdirect search method FLEXIPLEX was adopted to solve optimization object function. In order to find a global optimization solution, a random search method with iterative procedure was presented and their main features and calculation results were introduced.
