摘　　要：本文讨论带任意个充液腔的重刚体的自旋稳定性。以平均涡量作为液体的离散化变量,导出解析形式稳定性判据,并用于讨论充液自旋弹丸。对腔内隔板增强自旋稳定性的实际效果进行了估计。The spinning stability of a heavy rigid body with an arbitrary number ofliquid-filled cavities is discussed in present paper. The average vortex is used as a discretized variable of the liquid. A stability criterion in analytic form is derived and used to discuss the spinning projectile containing liquid charge. The effectiveness of the diaphragm on increasing the spinning stability is evaluated.
