摘要

Scatchard-Hildebrand公式是正则溶液理论乃至非电解质溶液理论的重要组成部分之一，也串联起内聚能、溶解度参数甚至范德华方程等诸多高分子物理关键知识点。虽然其推导并不必要，也罕见于教材之上，但是从实际教学效果来看，相当比例的学生希望更多地了解该公式的由来和详细推导过程，以辅助高分子溶液理论这部分的理解和公式运用。本文在名家的专业推导之外，面向教学过程汇总了该公式的发展和推导过程，以模拟其发明者的视角，更加生动地向学生介绍其从提出到成型的过程。

Abstract

The Scatchard-Hildebrand equation is one of the core components of the theory of regular solutions and nonelectrolyte solutions. It also links multiple key points of polymer physics such as the cohesion energy

solubility parameters and even the van der Waals equation. Although the derivation of the equation is not necessary and rare in textbooks

students demand more introduction to its origin and development history. Based on such introduction

students may better understand and utilize this equation. In this paper

the development and derivation process of the equation are summarized to assist the teaching. It serves as a supplementary to previous professional derivations

and a vivid introduction from the perspective of its inventors.
