摘　　要：将中医辨证理论和证候的获得过程与隐变量和隐结构分析的思想做了简要的对比分析,探索隐结构法对证候研究的实际意义。证候就像隐类分析一样是通过可见的"症状显变量"来探求内在的不可见的"证候隐变量",并建立证候隐变量和症状显变量以及证候隐变量之间的隐结构,但是传统中医证候的结构是由人脑从经验而习得的,而隐结构模型的构建则是由电脑基于相应的统计学原则,通过对临床流行病学所收集的症状数据分析所构建的。此模型不仅符合中医辨证理论,而且具有定量化的优势,可作为中医证候客观化和定量化的研究方法之一。TCM syndrome differentiation theory, syndrome acquisition process and latent variables, concealed structure thought were compared and analyzed briefly in this paper. The practical value of concealed structure method to syndrome study was discussed. The syndromes, as Latent Class Analysis （LCA）, search, internal invisible ＂ syndrome latent variables＂ through visible ＂ symptom significant variables＂, and to set up syndrome latent variables, symptom significant variables and a concealed structure among syndrome latent variables. But the syndrome structure of TCM is acquired from the experience of human brain, and concealed structure model is established by computer based on relevant statistical principle through the analysis of symptom data collected from clinical epidemiological survey. The model is accorded with TCM syndrome differentiation theory with quantitative advantage, and can be thought as one of research methods of TCM syndrome objectification and quantification.
