目的：基于形式概念分析理论，分析经方诊治情志病证的证治规律。方法：收集《伤寒论》及《金匮要略》中与情志病证相关的经方51首，基于形式概念分析理论，建立形式背景，生成属性偏序结构图，并从图中进行模式发现，从而总结经方诊治情志病的方药证治规律。结果：从方药属性偏序结构图及方证属性偏序结构图中，能系统、客观、全面地展示经方诊疗情志病的方证规律及方药配伍规律。结论：基于现代严密的形式概念分析数学理论，能有效解决中医内在辨证论治原理的描述问题，能从已知的数据中发现对诊疗有价值的知识，为中医经典传承提供新的思路与方法。

This study was aimed to analyze the regulation of syndrome-treatment pattern of classical Chinese medicinal formulae for emotional diseases based on formal concept analysis. First, we dealt with the decision formal context of 51 prescriptions about emotional symptom in the "Treatise on Febrile and Miscellaneous Diseases" and the "Essentials from the Golden Cabinet" based on the principle of optimization. Then, we generated a new partial-order attribute diagram in order to present the specific character. Finally, we explained properties of partial-order structure graph from traditional Chinese medicine (TCM) experts' point of view based on knowledge discovery. The results indicated the relationship between prescription and syndrome of emotional diseases. It was concluded that method proposed in this paper worked well in treatment of description of syndrome differentiation and discovery of new knowledge from the known data in the clinical diagnosis.
