摘　　要：在常用的拟合直线参数的估计中 ,往往没有考虑它们并非独立变量 .在分析了拟合直线参数的相关性后 ,给出了拟合直线参数比值的标准差的三种计算方法 .Linear fitting by least squares is a frequently-used method of processing experimental data,how calculate the standard error of parametric ratio of linear fitting is a problem should be attention in experiment.in this paper,parametric correlativity of linear fitting were analyzed,three calculating methods to standard error of parametric ratio of linear fitting were presented respectively.
