关于线性滴定的理论、方法及特点已有专门文献介绍,县体分为图解法和计算法两类.前者直观性强,对所用仪器的精度要求不高,但依靠手工作图,不仅费时费力,而且不免引入主观误差;后者计算繁杂,必须使用高功能电子计算机,本文在图解法基础上引入微机绘图,并自动剔除可疑值,再由微机进行回归处理,直接打印结果,测定时等量分步加入标准溶液4～5次,分别测出相应的响应值(无需到达化学计量 The theory, methods and features of linear titration have been introduced in the special literature, the county is divided into two categories: graphic method and calculation method.The former is intuitive and requires little precision on the instruments used, but it is not only laborious and laborious , But also inevitably lead to subjective error; the latter is complicated to calculate, you must use high-performance electronic computer, the introduction of computer graphics on the basis of graphic method, and automatically remove suspicious values, and then by the computer regression processing, direct printing results, Stepwise added to the standard solution 4 to 5 times, respectively, measured the corresponding response value (without reaching stoichiometry
