We propose a new method for studying stability which, in contrast to the traditional D-decomposition method, does not require knowledge of the characteristic equation. The method is effective in a wide class of problems in the dynamics of bodies with cavities containing a liquid.

液体旋转系统旋转稳定性的研究

我们提出了一种新的稳定性研究方法，与传统的D分解方法相比，它不需要特征方程的知识。该方法在具有包含液体的空腔的物体的动力学中解决各种各样的问题时是有效的。
