摘要：
The phase diagrams of a site-dilute Ising model with a random field are studied within the framework of a one-spin cluster approximation. Tricritical points and reentrant phenomena are discussed. The influence of the random field on the critical concentration of magnetic atoms at which the transition temperature reduces to zero is also investigated.
