摘　　要：报道了谐振子模型和Ｋｒａｍｅｒｓ－Ｋｒｏｎｉｇ关系相结合在晶体长波光学声子红外反射光谱上的应用。The synthetical application of the oscillator model and Kramers Kronig relation to the far infrared reflection spectrum of the long wavelength optical phonon in crystals was reported. By using the restriction condition between the oscillator model and the Kramers Kronig relation, a method was proposed to reckon the dielectric function from the incomplete far infrared reflection spectrum.
