| 摘 要： | 在离心力和重力作用下的半充液球腔内液体晃动的特征值问题，源于以角速度ω０ 自旋刚体上半充液球腔的偏置，是一种边界条件复杂的三维问题。用边界元方法对问题 进行了计算，并对结果进行了分析．为进一步用Ｃａｌｅｒｋｉｎ方法定量分析带偏置半充液 球腔的刚体的运动稳定性提供了基础。

| Abstract: | The boundary element method is applied to study the eigenvalue problem of liquid sloshing in off-centred spherical cavity on a rotating body. The numerical results are in coincidence with the theoretical results and are the basis for analyzing the stability of such rigid body having such cavity filled partly with liquid. |
