摘　　要：本文导出质子平衡方程:Y=[H]-[OH]+(SHB-S×C_f)×F_o-Z×C_d×F_v=0为布朗斯台特体系酸碱平衡计算编制应用程序提供通式,应用这个方程,给出了氢离子浓度的计算程序,运行结果满意,此外作者还导出了几个数学通式,用于绘制滴定曲线,估算滴定误差,描绘缓冲容量曲线以及处理线性滴定法的分析数据等等。这一切都将有助于拓宽和深化分析化学课中有关中和滴定基本原理的内容。In this paper,proton balance equation, Y = [H] - [OH]-KSHB-S×Cf) × Fo- Z × Cd × Fv = 0, to write a universal utility program fcr calculation of acid-base equilibria in bronsted systems is derived,Using this equation,a calculated program of the hydronium ion concentration (pH ) has been given. The running results are satisfactory .The author also derived several general mathejaatieal expressions,which can be used for drawing titration curves, evaluating titration error,describing capacity curves of buffer solution and treating analytical data of linear titration method, etc. All these results will contribute to broadening and deepening the fundament of neutralization in analytical chemistry course.
