摘　　要：用计算机对离子选择电报分析数据进行处理.程序采用BASIC语言编写,在PC-1500A型计算机上实算通过.以一、 二价离子电极的实验数据为例.比较了标准曲线法。标准加入法中的已知电极斜率计算法和未知电极斜率的数值逼近法对所得结果准确度的影响.对文献中的一些实验数据进行了同样的处理.以便比较.Experimental datas obtained in ISE analysis using of standard solution put-in method are processed by a pocket computer SHARP PC-1500A and a program designed with BASIC language. Original datas are obtained from determination done by ourself and published documents as well. These datas are processed by different methods including Calculation based on known Nernst Slope of Electrode and Numerical Approximation methods which do not need the slope. Effects of these methods on the results are compared. The results are good in line with those of documents. It was suggested that the results of Calculation using accurate formulas, accompany with an additional datas assessment, is more reliable and stable.
