| 摘 要： | 根据Ivaska直线交点处理法的思想,提出一种能剔除电位滴定较差数据点,含有二元未知参数酸碱体系的计算方法。由于采用统计原理取舍数据,计算机进行全过程运算,不仅减少了原手工作图、目测判断的误差,而且大大提高了计算速度和精度。并且将此法推广应用于任意多元酸的二元混合物体系,同时编制了“IVASKA—PLOT(CO—PK)”计算机程序。

| Abstract: | Based on the thought of Ivaska's treatment of lines intersection point by means of computer artd statistical theory, a improved method is presented. Both graph and adjudgement of results are carried out by computer, instead of handwork and visualization by human. And it has been extended to the mixture of two polyhydric acids. A computer program"lVASKA-PLOT(CO-PK)", with plotting results and consulting data, has also been givan. Several systems were testified with satisfaction. |
