摘要：
The phase diagrams of the spin-1/2 transverse Ising model with random interactions are investigated within the framework of the effective field theory using an improved configurational averaging procedure. General formulae, applicable to lattices with coordination number z, are given. Numerical results are presented for a simple cubic lattice. It is found that the effects of a transverse field on the phase diagrams exhibit a number of interesting phenomena.
