Pearson软硬酸碱(HSAB)原理是从广义酸碱概念对化学物质进行分类的一个重要尝试,这种经验的分类对整理庞杂的化学数据、预测某些化学反应有着积极的意义,Finston等进行了系统综述。这方面的研究要上升到理论阶段需从微观方面例如用量子化学计算进行探讨,但化学现象极其复杂,目前这方面的研究尚存在一定困难。值得注意的是,在行为科学等似乎无法定量研究的领域中应用数理统计方法 The Pearson HSAB principle is an important attempt to classify chemicals from the generalized concept of acid-base. The classification of this experience is of great importance for organizing complex chemical data and for predicting certain chemical reactions. Finston et al. A systematic review. In this respect, the research going up to the theoretical stage needs to be discussed from the microscopic point of view, for example, using quantum chemical calculations. However, the chemical phenomenon is extremely complicated. At present, there are still some difficulties in the research of this aspect. It is noteworthy that the use of mathematical statistics in areas where behavioral science seems to be unable to be quantitatively studied
