The theoretical physics model for relation between the nucleation and the solution convection was established under the two-dimensional coordinate systems. The results indicated that under periodical boundary condition, the cycle oscillation (vibration) solution would appear as long as the fluxion speed of liquid along two coordinate axes isn't zero. The ammonium choloride crystal was dissolved in water to obtain the solution of ammonium choloride, and the solution was heated until the temperature was above the supper saturation temperature, then the solution was cooled naturally up to 3.7°C above the supper saturation temperature and stired, a number of nucleation came out and grew to NH 4Cl crysal. This was agreed with the results obtained from the theoretical model.
