Scaling law in thermal phenomena

In this paper the scaling law for the relaxation times in thermal phenomena is investigated. It is shown that dependent on the value of the parameter K=E/m(c\alpha)^2,where E is the energy which is delivered to the system, m is the parton mass and \alpha=1/137 for electromagnetic interaction and \alpha=0.16 for strong interaction respectively, heat transport is diffusive, for K<1, or contains the wave component for K>1. For the system with N partons the relaxation time is scaled as \tau^N\to N (\hbar/(mc\alpha)^2). Key words: Thermal phenomena, scaling
