摘　　要：目的为中医诊断中的症状体征建立一个综合评价指标———广义指标。方法基于熵评价函数的广义指标建立方法。结果通过与主成分分析法和非线性主成分分析法分析的结果进行对照,在3种方法分析的结果中,只有基于熵的广义指标方法能够体现症状体征的总体特征,并符合临床经验。结论利用基于熵的广义指标建立方法对中医诊断系统建立定量的综合评价指标是可行的,对中医治疗的临床疗效进行定量评价有重要作用。Objective To set up a synthetic evaluation index, a generalized index, for symptoms and and nonlinear PCA were compared. The establishment method of generalized index based on entropy only reflected the total characteristics of symptoms and signs and met the clinical experiences. Conclusion It is workable to set up the quantitative synthetic evaluation index in Chinese medicine diagnostic system through the establishment of the quantitative evaluation of generalized index based on entropy. The method plays an important role in curative effect of Chinese medicine.
