In the paper, rapid calculation preprocessing model of particle’s interacting N-body problem is discussed. Coordinate of particle is approximately replayed by grid center. According to the similarity of grid’s topological structure, concept and algorithm of basic solvable range and basic insolvable range of radial distribution function are put forward. In advance, distance function and class partition function between cell centers is found, radial distribution function is computed by translation transformation. In this paper, examples indicate that approximation algorithm is of computing time short and error small, so the approximation algorithm has stronger practicability.

Rapid Calculation Preprocessing Model of N-Body Problem

The structure of molten LiF-KCl solution has been simulated by Monte Carlo method.The partial radial distribution function of ions,the molar volume,enthalpy and the heat of mixing of LiF-KCl melt have been calculated. Some results of calculation agree with experimental data.The results of calculation indicate that the average distance between Li~+ and F~- ions decreases significantly after the mixing of molten LiF with KCl, and the free volume distribution of the LiF-KCl melt is far from uniform.
