本文提出一个电导滴定分析数据自动处理程序。此程序用BASIC语言编写,在LASER 310微型计算机上通过,试算结果正确,适应性较强。数据输入以后,从数值计算、条件判断、结果打印一直到绘制坐标轴、滴定曲线与拟合折线均可自动连续完成。采用二阶差分商的绝对值与临界值比较的方法判断电导滴定曲线突变的开始与终止,用以自动划定观测点的线性范围。
This paper presents an automatic titration analysis data processing program. This program is written in BASIC language, passed on the LASER 310 microcomputer, the trial results correct, strong adaptability. After data input, from the numerical calculation, the condition judgment, the result printing until the drawing coordinate axis, the titration curve and the fitting polyline can be automatically and continuously completed. The absolute value of the second order difference operator is compared with the critical value to determine the beginning and end of the abrupt change of the conductometric titration curve to automatically delineate the linear range of the observed point.
