摘要: 分3种情况讨论了光栅位置倾斜对测量谱线波长的影响,利用数学软件Mathematica作图估计其大小,并分别与仪器误差的影响作了比较,指出对于消减测量的系统误差,有些调整步骤是必要的,有些则是出于训练调整分光计的目的.

Abstract: The influences of a non-perpendicular diffraction on the wavelength are discussed in three aspects. The figures are plotted by using the Mathematica program,the error is evaluated and compared with the influence of the instrument permitted error.We conclude that some of the adjustments of the spectrometer are necessary,and some are due to the purpose of training.

Key words: diffraction grating, non-perpendicular, wavelength, influences, Mathematica
