摘　　要：把红外光栅光谱仪测得的衍射光强分布和待研究的光谱分布用积分方程相联系,利用希尔伯特—史密特理论解积分方程,实现衍射光谱的消卷积,进而可得到高分辨率的复原光谱。The distribution of diffraction intensity measured in an infrared grating spectrometer and the spectrum to be studied are related with two integral equations. Using the theory of Hilbert and Schmidt, the decoavolution of the diffraction spectrum is realized. Further, the original spectrum is recovered with a high resolution.
