The slope of titration curve is at a minimum . 滴定曲线的斜率处于最低值。
The initial ph of solutions of poorly ionized acids depends largely upon the degree of ionization and the titration curves very markedly . 其电离酸溶液开始的pH值在很大程度上取决于电离度,其滴定曲线也非常清晰。

The results shows that the repeatability and accuracy are both better than before by using the titration curve or differential curve to determine the destinations 结果表明,采用滴定曲线或徽分曲线确定终点,测定结果的重复性和准确度均有较大提高。
This paper accomplishes the following researches : firstly , the paper analyzes the characteristics of ph and orp by means of lots of experiments , which show that both ph and orp are nonlinear and have large lag 本文主要包括以下几部分内容:首先,在大量实验的基础上分别分析了ph和orp的对象特性。实验表明, ph和orp都是非线性、大滞后的对象,而且orp的滴定曲线存在很大的不确定性。
