摘要：
We demonstrate that if the exponent gamma that measures nonsmoothness of the velocity field is small then the isotropic zero modes of the scalar's triple correlation function have the scaling exponents proportional to root gamma. Therefore, zero modes are subleading with respect to the forced solution that has normal scaling with the exponent gamma.
