| 摘 要： | A new approximate scheme which is combined by the mean-field renormalization group theory (MFRG) with the discretized path-integral renormalization (DPIR) is employed in the study of the disordered tranverse Ising model (TIM). The critical properties of random-bonds Ising systems on a d-dimensional lattice are calculated with this new approximate scheme.
