首先，我讨论了之前对恒星超射进行量化的理论尝试的五个谬误。然后，我建议唯一可靠的方法是求解关于对流通量、动能和势能、湍流压力和动能耗散率的五个动力学方程，加上平均温度方程。最后，我讨论了新模型的最新解，它与最新的日震学OV数据相一致，并建议使用相同的数据来检验Schwarzschild准则的有效性。
First, I discuss five fallacies of previous theoretical attempts to quantify overshooting in stars. I then suggest that the only reliable procedure is to solve the five dynamic equations for convective flux, kinetic and potential energy, turbulent pressure and dissipation rate of kinetic energy, plus the mean temperature equation. Finally, I discuss a recent solution of the new model that agrees with the latest helioseismological OV data and suggest that the same data be used to check the validity of the Schwarzschild criterion.
