摘要：
A lattice gas model equivalent to the t-J model is proposed, in which the spins are represented by Bose particles with spin and the holes by Fermi particles with spin. In the zero hole density, the model reduces to a lattice gas of Bose particles with spin, equivalent to the Heisenberg model, where the average occupation number of a lattice site is unity, while a lattice site can accomodate two particles.
