摘　　要：利用光滑样条非参数模型和百分位数法,在6.11版SAS软件包上构建了香港地区0～7岁儿童体重生长发育的百分位数曲线、体重生长速度和生长加速度曲线,结果表明非参数模型能够最佳地兼顾拟合优度和光滑度,改进了经典LS法,可作为生长曲线拟合的一种优异方法而广泛应用于医学领域.Based on package SAS 6.11, centile curves and velocity curves and acceleration curves for children's weight at ages 0～7 years in Hong Kong were constructed by using nonparametric model and centile of smoothing spline.Nomparametric model would compromise between goodness of fit and smoothness, and improve classical LS method. It would be widely used in various medical research fields as an excellent methods of growth curve fitting.
