摘要：
A new method for the calculation of the equation of state for the three-dimensional Ising model is proposed. The case of a simple cubic lattice with an exponentially decreasing potential is considered. Solutions of the equation of state near the critical point are obtained as the functions of temperature, external field and microscopic parameters of the system. The surface of the equation of state for certain potential parameters is constructed.
