【 摘 要 】

Two- and three-dimensional random Ising models with a Gaussian distribution of couplings with variance J and nonvanishing mean value J(0) are studied using the zero-temperature domain-wall renormalization group (DWRG). The DWRG trajectories in the (J(0),J) plane after rescaling can be collapsed on two curves: one for J(0)/J>r(c) and the other for J(0)/J
