摘要：
We investigate a model which differs from the Ising model in transverse field with random-bonds by the addition of an interaction term in transverse direction. Such a model is analyzed by the effective Hamiltonian method extended to random system. The critical properties of the system are considered and the phase diagram is derived. The role of the transverse interaction term is examined.
