反映脉图频域指标增龄变化规律的数学模型尚未见文献报道 ,本文应用逐步回归分析法从脉图频域指标中选择一些作用显著的自变量 ,以建立多元回归方程 ,并对其进行临床检验。1　对象和方法在体检中挑选经病史、体检和心电图、血脂等常规检查无明显心血管和其他内脏疾病者作为正常 The mathematical model that reflects the change rule of pulse frequency domain index in aging has not been reported yet. In this paper, stepwise regression analysis is used to select some influential independent variables from the pulse frequency domain index to establish multiple regression equation and to conduct clinical test. 1 Subjects and methods in the physical examination in the selection history, physical examination and ECG, blood lipids and other routine examination without obvious cardiovascular and other visceral disease as normal
