摘要
对旋转对称中心贮箱内的自旋液体晃动问题，提出了一个直接对Ｅｕｌｅｒ方程进行Ｇａｌｅｒｋｉｎ离散的近似方法，并分析了方法的近似性。
The slosh problem of spinning liquid in an axisymmetric container has beeninvestigated in the present paper. A PEG method has been suggested here to remedy thetheoretical defect caused by using the traditional PBG method. This paper also analyses thestability of free vibration of spinning liquid in the rotating container with constant angularvelocity.
