摘要：

Analysis of experimental data on the structural relaxation time tau(alpha) in various glass formers revealed its universality at the critical temperature T-c of the mode-coupling theory. In most glass formers studied ln tau(alpha)(T-c) = -(6.5-7.5). Possible reasons for such a universality are discussed.
