摘要：
The critical behavior of a quenched random hypercubic sample of linear size L is considered, within the "random-T-c" field-theoretical model, by using the renormalization group method. A finite-size scaling behavior is established and analyzed near the upper critical dimension d = 4 - epsilon and some universal results are obtained. The problem of self-averaging is clarified for different critical regimes.
