<正> In this paper the action of vortices on each other is considered. It is assumed that the homogeneous and isotropic turbulent field is composed of vortices and pairs of vortices distributed homogeneously in space. Using the picture of turbulent field, the numerical result of double-velocity correlation f(γ/λ) is larger than the result of turbulent field composed of vortices only. These results are in agreement with the experimental data obtained by J, C. Bennett and S. Corrsin.
