摘要
Ⅰ. INTRODUCTIONResponse functions containing infrared divergence effects are given in this paper. These functions assume the same form for NMR relaxation, dielectric loss and internal friction. Except the constant factor, T1-1, X″/βω and Q-1/βω have the same frequency and temperature dependence. Forthermore, in Na β-alumina in three cases, the exponents N of infrared divergence are all equal to 0.7. The theoretical apparent activa-
