摘要：

The scaling properties of the temperature structure functions are experimentally investigated in turbulent Rayleigh-Benard convection at low Prandtl number. It is found that the temperature has the same scaling exponents of a passive scalar in 3D homogeneous isotropic turbulence. These exponents are obtained from the property of extended self-similarity, extending the scaling laws to the case of moderate Reynolds numbers.
