本文给出了自引力三轴椭球在任意转动状态下内部应力张量的一个简洁公式。它在不可压缩介质极限下不含奇异性。的应力张量和品质因子模型被用来推导出的阻尼（短轴模式）或激励（长轴）的摆动导致的能量耗散的解决方案。在旋转椭球的限制，我们比较我们的解决方案与以前的，并表明，适当的修正，阻尼时间估计的差异要小得多，比它一直声称。
A compact formula for the stress tensor inside a self-gravitating, triaxial ellipsoid in an arbitrary rotation state is given. It contains no singularity in the incompressible medium limit. The stress tensor and the quality factor model are used to derive a solution for the energy dissipation resulting in the damping (short-axis mode) or excitation (long axis) of wobbling. In the limit of an ellipsoid of revolution, we compare our solution with earlier ones and show that, with appropriate corrections, the differences in damping times estimates are much smaller than it has been claimed.
