具有对流包层的恒星的平衡潮汐理论被批判性地重新审视，考虑到最近的发展，并在混合长度方法中以最一致的方式处理热对流。识别并讨论了薄弱环节，特别是潮汐周期短于对流周转时间时湍流粘度的降低。导出了控制此类邻近双星动态演化的长期方程的改进版本。
The theory of the equilibrium tide in stars that possess a convective envelope is reexamined critically, taking recent developments into account and treating thermal convection in the most consistent way within the mixing-length approach. The weak points are identified and discussed, in particular, the reduction of the turbulent viscosity when the tidal period becomes shorter than the convective turnover time. An improved version is derived for the secular equations governing the dynamical evolution of close binaries of such type.
