It Is realized the theoretic - field description of Ising systems behaviour with effect of long-range interaction in two-loop approximation in three-dimensional space with using Pade-Borel resummation technique. The renorm-group equations are analysed and it is chosen fixed points, defining critical behaviour of the system. It Is shown that the influence effect of long-range interaction can bring as to change the mode of the critical behaviour, so and to change the type of the phase transition.
