摘要：

Using the finite cluster approximation, the phase diagram of site-diluted three-dimensional simple cubic Ising models with a random field is determined. The phase diagram exhibits only second-order transition or second-order and first-order transition lines, according to an appropriate probability distribution of these random variables,
