摘要: On the basis of Onsager's phenomenological equation motion, generalized form susceptibility is derived. This includes damped harmonic oscillator (DHO), Van Vleck-Weisskopf and Frohlich (VWF) Debye relaxational model as different limiting cases, equivalent to that obtained from Bloch for Ising in a transverse field which are used pseudo-spin KDP-type crystals. Characteristics mutual relations susceptibilities discussed with an emphasis on difference between DHO VWF. For heavily mode, becomes difficult physically interpret since eigenfrequency damping factor may lose their original meaning. In such only important parameter distance origin pole χ(ω) complex ω-plane.
