摘　　要：以信息覆盖为准则，依靠少量信息，建立了心功能曲线的灰色模型和数学回归模型，误差检验灰模型的精度明显高于数学回归模型，在分析了心功能曲线的生理特性和发展变化特点的基础上，提出了心功能曲线的闸门－激活式联合灰模型理论及计算ｋ至ｋ＋１灰区间模型值的映射量化方法．Using the principle of information covering, the grey model as well as the regression model for the ventricular function curve have been developed with only a small amount of information. Error checking shows that the accuracy of the grey model is obviously superior to that of the regression model. Based on the analysis of the evolutional feature and physiological character of ventricular function curve, the sluice activation GM (1,1,0,2) and its error GM (1,1) combined grey model, or the mapping quantification theory and method to calculate the grey model values between the internals k and k+1 are proposed.
