不考虑大气压力作用下,物体所受浮力的大小不仅与ρ液、V排和g有关,还与物体表面积s、浸入液体深度h以及接触系数k有关.那么如果考虑大气压力作用,结论是否变化.从理论分析、公式推导两条路径进行了讨论,得出结论:物体与容器底壁部分紧密接触时,浮力不仅与ρ液、V排和g有关,还与物体表面积s、浸入液体深度h以及接触系数k有关,使得该问题的研究更为圆满,为教学提供参考.

Without considering the atmospheric pressure,the size of buoyancy depends on not only the density of gasoline,the volume of the displaced liquid,but also on the object′s surface area,the immersion depth and the contact coefficient k . However,when taking high atmospheric pressure into consideration,does the conclusion change.Have a further discussion on the problem,and draw the same conclusion at last,which is more successful for the teaching to provide further reference.
