以物料平衡、电荷平衡和化学平衡为基础，通过严格的数学推导提出一种新的滴定分析理论──相对滴定法．它是以相同滴定状态下（如ｐＨ、ｐＭ、电位、吸光度等）被测物质的量与滴定剂体积之间的线性关系为基础，通过仪器分析方法（如标准曲线法、标准加入法等）进行定量计算．该法在滴定过程中的任一状态都成立，不需确定等当点，从根本上消除了终点误差，不仅适用于滴定突跃很小的体系，还适用于滴定反应未知的滴定过程．本文以强碱滴定一元弱酸为例，通过系统的误差分析，确定了影响相对滴定法精度、灵敏度的因素及选择最佳实验条件的方法，并通过强碱对硼酸的滴定进行验证，结果与理论分析完全吻合．
On the basis of material balance, charge balance and chemical equilibrium, a new theory of titration is proposed through strict mathematical derivation - relative titration. It is based on the same titration (pH, pM, potential, absorbance, etc.) the relationship between the amount of test substance and the volume of the titrant based on the linear, through instrumental analysis methods (such as standard curve method, standard addition method, etc.) Quantitative calculation. This method holds true for any state in the titration process. It does not need to determine the equivalence point, and ultimately eliminates the end point error. It is not only suitable for the system with small titration jumps but also for the titration process with unknown titration reaction. In this paper, the strong alkali titration of a weak acid as an example, through the systematic error analysis to determine the relative titration accuracy and sensitivity of the factors and the choice of the best experimental conditions, and the strong base of boric acid titration to verify the results and the theory Analysis is completely consistent.
