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。
In order to fit the dispersion curve with the measured data, the coefficients are deternfined by the least square solutions to the overdetermined equations of Cauehy＇s formula, these eoeffieients are eompared with the nonlinear least square fitting measured data in Origin Software. The results show that both are maintaining eonsisteney in the experimental rotors.
