Turbulent convection models (TCM) provide a better way to study convection in stars than the MLT. Improving numerical method, we adopted larger diffusion parameters and smaller dissipation parameters in order to further correct the p-mode oscillation frequencies of TCM models. The density gradient reversing is discussed.
