Popis:	A new simple analytical approximation for calculations of the shortrange order parameters and their Fourier transform in disordered binary alloys with a Bravais crystal lattice and with atomic interactions of arbitrary effective radius of action is proposed. On the basis of the comparison with the Monte Carlo simulation data, the high numerical accuracy of approximation is demonstrated and it is shown that this accuracy turns higher with the increase of the effective radius of atomic interactions. The developed approach may be also followed in studies of magnetics within the framework of the Izing model, of fluids and amorphous materials within the lattice gas model as well as in investigations of the low-dimension lattice systems.
