了解多价电解质的解离机制仍然至关重要。不同的理论方法可能会导致所分析系统的微观参数及其整体特性（例如电导率和缓冲能力）产生不同的值。这里提出了解离方案的统一分类。考虑了混合型方案的一些例子，并给出了有关宏观和微观常数的表达式。考虑将 Linderstr phi m-Lang 方程应用于总浓度不恒定的多离解系统的可能性。讨论了质子结合曲线（所谓的滴定曲线）建模问题。 (C) 1999 Elsevier Science B.V. 保留所有权利。
Understanding of the dissociation mechanism for polyvalent electrolytes remains a matter of critical importance. Different theoretical approaches could result in different values for the microscopic parameters of the system under analysis, as well as for its integral characteristics (such as conductivity and buffering power). A unified classification of dissociation schemes is proposed here. Some examples of hybrid type schemes are considered and the expressions relating the macroscopic and microscopic constants are given. The possibility of applying the equation of Linderstr phi m-Lang to multi-dissociating systems with non-constant total concentration is considered. The problem of proton binding curves (so-called titration curves) modeling is discussed. (C) 1999 Elsevier Science B.V. All rights reserved.
