摘要
A model of nonlinear oscillators related to classical electrodynamics is studied. Using an indicator based on the energy exchange of harmonic modes, it is possible to establish that equipartition of energy and equipartitions of exchanges go hand inhand: this entails a phenomenon of quasi-harmonic behavior of high modes which we call "superfreezing". Comparisons with similar experiments on other models where superfreezing does not occur, seem to indicate the kind of nonlinear coupling and the shape of the spectrum as responsible for this phenomenon. © 1990.
