  Based on Nowick's self-induced ordering theory, we develop a new
configurational-entropy relation to describe the non-Arrhenius
temperature(T)-dependent relaxation in disordered systems. Both the
configurational-entropy loss and the coupling interaction among relaxing units
(RUs) are explicitly introduced in this relation; thus, it offers a novel
connection between kinetics and thermodynamics that is different from the
Adam-Gibbs (A-G) entropy relation, and it generalizes several well-known
currently used relations. The present relation can provide direct and more
accurate estimates of (i) the intrinsic activation enthalpy, (ii) the
T-evolvement of the systematic configurational entropy loss and (iii) the
self-induced ordering temperature Tc, which characterizes the coupling
interaction among RUs. Application of the theory to experimental
relaxation-time data for typical organic liquids demonstrates its validity.
