摘　　要：以直线交叉法为依据,根据最小二乘原理,采用Matlab GUI工具设计了一款用于计算二元共聚合反应竞聚率的图形用户程序。与传统的求解竞聚率方法相比,该图形用户程序具有设计原理简单、计算快捷的特点;同时程序提供界面简洁、交互友好的数据输入平台,实用性强。实际应用表明:采用该款图形用户程序所测得的数据与微机动态搜索法、Tidwell-Mortimer法相近,而比采用斜率截距法计算竞聚率的最小差方和更小,并且也避免了采用斜率截距法由于所用方程的非对称性造成的计算结果的不一致性。Based on linear intersect, the graphic user program of reactivity ratio of two-component copolymerization calculation was designed according to least squares principle by using Matlab GUI in the paper. Compared with traditional approaches of reactivity ratio solution, this graphical user program has the characteristics of simple design principle and fast computation. In addition, the terse interface, friendly interaction and practical input platform was provided by Program. The results of actual application indicated that the data by using graphic user program are closed to the value which calculated by microcomputer dynamic search method and Tidwell-Mortimer method, and much more smaller minimum sum of squares of deviations than using slope-intercept method. Avoiding the inconsistency of calculation result which caused by equation asymmetry of slope-intercept method.
