摘　　要：利用光栅光谱仪测量了加法基色和减法基色的透射光谱,并借助2个不同滤波片的组合可以实现减法混色的物理过程.同时,通过实验证明了色光波长会随着入射角增大而向短波长偏移.The spectra of additive tricolor and subtractive tricolor are measured using a spectrometer. The process of subtractive color mixing is achieved with combinations of any two of six tricolor filters. Especially, it is found that color lights wavelength will shift towards short-wavelength along with increasing incident angle of light beam.
