Various Representations of Multi-Relaxation in Solids with Discrete Relaxation Spectra

Abstract
A multilinear relaxation of any kind may have various representations which aid to comprehend natural phenomena concerning not only anelastic relaxation but also dielectric, magnetic and thermal relaxations. Five representations are given : representation 1 by n+1 non-equivalent conjugate variables composed of density and partial potential, representation 2 by a Voigt-type general linear solid of order n, representation 4 by a Maxwell-type general linear solid of order n, representation 4 by n different δJ⁽ⁱ⁾(i=1,2,..,n) or n different δM⁽ⁱ⁾(i=1,2,..,n) , and representation 5 by n Debye peaks of internal friction.
