摘要
研究了比率相关同时评价问题。利用２种实验数据（几种截面及其相应的比值）来求截面的拟合值，并给出误差估计。将截面值的对数用样条函数来逼近。按广义最小二乘法推导计算公式，并介绍、分析算例。
The simultaneous evaluation relative to ratio is discussed.The experimental data of somekinds of cross sections and their ratios are fitted,the fit values and their errors are calclated.Thelogarithms of the cross sections are approached with spline function.the calculation formulas are deduced with generized least square method. Some examples are given and analyzed.
