基于回归分析方法的氢原子光谱数据处理

Data Processing of Hydrogen Atom Spectroscopy Based on the Regression Analysis Method

利用回归分析方法,对改进的小型摄谱仪测氢原子光谱实验的数据进行了处理。回归分析表明:由棱镜玻璃的折射率随波长的非线性引起的波长与位置读数的关系,如果用二次多项式表示,则显著拟合在α等于0.1水平上。故只需二次方程就能表示波长与位置的关系,由此得出氢原子光谱的波长。该方法适用于一切具有未知函数规律的数据处理问题。

The regression analysis method is used to deal with the data of the hydrogen atom spectroscopy experiment measured by small spectrograph. The relationship between wavelength and location data are risen by non - linear of refractive index of prism glass. If this relationship is shown by quadratic polynomial, fitting is significant at the level when α= 0. 1. In that way, this relationship could be known by using quadratic polynomial. In addition, wavelength of spectra of hydrogen atom could be obtained. This method is applicable to all the data processing problems with unknown function laws.
