先回顾一下物体的浮沉条件,我们可以从两个角度认识这个问题:物体重力与所受浮力的大小关系;物体密度与液体密度的大小关系:
First of all, to review the object's surface conditions, we can understand this issue from two perspectives: the object gravity and the size of the relationship between the buoyancy; object density and the liquid density of the relationship:
