Abstract: This paper uses weightiness method based on partial-differential coefficient to analyze the weightiness for gan-yang-shang-kang symptom in TCM，and the syndrome grade affected tracks are drawn by the analysis.On the above base，approach is gone deep with data mining，and the result that symptoms how to affect gan-yang-shang-kang syndrome in given conditions is given out.According to the analysis and result，a tentative diagnosis-treatment model is put forward.

Key words: weightiness method, grade affected track, Traditional Chinese Medicine（TCM）, gan-yang-shang-kang syndrome, weightiness for symptom

摘要： 应用偏微分效用分析方法对中医肝阳上亢证的症状敏感性进行了研究，绘制出了程度影响参考曲线。在此基础上，又对研究对象进行了深度挖掘分析，得出了在限定性条件下症状对肝阳上亢证影响敏感性的一般性结论。提出了诊断－治疗参考模型的设想。
