摘要：

After improving the Monte Carlo statistics, Derrida's exponent theta for the never damaged sites in Ising models at finite temperatures is shown to be compatible with theta(T = 0) = 0.22 in two dimensions. In three and more dimensions the number of these sites decays differently from zero temperature.
