The nonequilibrium relaxation method is extended to the spin glass and the Kosterlitz-Thouless(KT)systems. The critical universality including the dynamical one is mainly analyzed. The universality in random system is observed for the static exponents while no universality appears for the dynamical one in the ferromagnetic transitions. On the other hand, it does not appear for the static exponents but for the dynamical one in the KT phase. This result leads us to subjects which have not been investigated much. As for the analysis of the spin glass system, the present study makes us possible to discuss the structure of universalities whole in the phase diagram.
