摘要：

为了用实验数据拟合色散曲线，通过求解柯西公式系数的超定方程组最小二乘解来确定系数的值，并与Origin软件非
线性最小二乘法拟合测量数据进行比较。结果表明，在实验误差范围内两者吻合得很好。

关键词: 色散曲线, 超定方程组, 非线性最小二乘法, Origin

Abstract:

In order to fit the dispersion curve with the measured data, the coefficients are determined by the least square solutions to
the overdetermined equations of Cauchy's formula, these coefficients are compared with the nonlinear least square fitting measured
data in Origin Software. The results show that both are maintaining consistency in the experimental errors.

Key words: dispersion curve, overdetermined equations, nonlinear least square, Origin
