摘　　要：首先,指出通常浮力定义的文字并不够完整和全面;然后,分析了一种直线加速参考系中的浮力,得到明确的结果;再后,通过对密度随深度递增的静止流体中浮力作用线的分析,指出浮力的作用线通过排开流体的重心应更准确;最后,给出了在考虑到非惯性系和流体密度不均匀后,关于浮力定义更一般的表述.The article first points out that the usual text used to define buoyancy is not complete and comprehensive enough;then,the buoyancy in a linear acceleration reference frame was analyzed,and clear results were obtained;later,through the analysis of the buoyancy action line in a stationary fluid where mass density increases with depth,it is pointed out that the buoyancy action line should be more accurate when passing through the center of gravity of the fluid;finally,a more general expression on the definition of buoyancy is provided,taking into account non inertial frames and uneven fluid density.
