摘　　要：根据流体静力学的结论,计算了重力场内匀质、静止流体中刚性物体在三种不同情形下所受的浮力,与阿基米德原理给出的结论一致。计算和讨论过程加深了对浮力本质的认识。Principle of Archimedes is important way to compute buoyancy of object in the fluid. In gravitational field, we use basics principle of fluid statics, analyze buoyancy of object in the invariant density and static fluid , and obtain buoyancy of object in three different condition. It is indication that, we obtain buoyancy of object in three different condition agree with principle of Archimedes. In the process of calculation and discussion, we can understand the essence of buoyancy.
