有色络合物组成的测定常采用平衡移动法及连续浓度变更法。由于手工作图效率低,且不易获得精确结果。本文在文献所述方法原理的基础上,编写了 PC—1500计算机处理数据、绘图、打印络合物组成的两个程序。经实例验证可行,使用简便、计算结果精确。程序特点如下所述。程序1(平衡移动法):按改进平衡移动法测得数据送入计算机后,计算机将数据作曲线回归(数学模式:y=ax~2+bx+c)。并对曲线方程求导,以相邻两个测定点的相应导数值之积 (?)判别是否存在极值(极大或极小)。如有极值存在((?)<0),分别从 Determination of the composition of non-ferrous complexes often use the balance of mobile method and continuous concentration change method. Due to the low efficiency of manual mapping, and not easy to get accurate results. Based on the principle of the method described in the literature, this paper prepares two programs consisting of PC-1500 computer processing data, drawing and printing complex. The example verified feasible, easy to use, the calculation accuracy. Program features are described below. Procedure 1 (Balanced Movements): The data is fed back to the computer as measured by the improved balance shift method. The computer then returns the data as a curve (mathematical model: y = ax ~ 2 + bx + c). Then, the equation of the curve is derived and the extremum (maximum or minimum) is judged by the product of the corresponding derivative values ​​of two adjacent measuring points (?). If there is an extreme value ((?) <0), respectively, from
