摘要
本文对曲线拟合优度的检验问题提出了一种可以量化的检验方法，解决了长期以来只能定性评价曲线拟合优度的问题。该法从直接讨论拟合值ｙ与实测值ｙ的接近程度出发利用已经成熟的直线相关回归的理论和方法给出了推断曲线拟合效果优劣的一个明确标准。
his article develops a quantitative test method that tests the goodness of curve fitting. This methodsolves the question that we only can,up to now,qualitatively criticize the goodness of curve fittin. From di-rectly disctissing the simllar degree of the estimations and adtual valtues,by correlation that has been alreadyvery mature,the author found a more accurate standard that criticizes the result of curve fitting.
