On the basis of intrapair and interpair correlation model, we have calculated the pair correlation energies of different kinds of systems, analyzed the changing rules of correlation energies of various electron pairs, and developed a reasonable and simple scheme called "Separating Large System into Smaller Ones". The basic idea of this scheme is that the correlation energy contributions of actual components in the ionic compound can be obtained using the correlation energy of ions with integer charge as the boundary conditions and incorporating the HF wave function or the distribution of electron cloud, then the total correlation energy of the system can be estimated by linearly summarizing the correlation contributions of these components.
