| Research Abstract |
Analyzing the characteristic features seen in various glass-forming liquids near the glass transition from a unified point of view based on the mean-field theory recently proposed by the present researcher, Tokuyama found the following important two types of universalities :
(1) If the self-diffusion coefficients of different atoms in two different systems have the same value, the dynamics of each atom obeys the same master equation.
(2) The self-diffusion coefficient of atom obeys a master equation, even if it belongs to different multi-component liquids.
