学过流体静力学的学生都知道阿基米德原理是:“浸在流体中的物体(全部或部分)受到向上的浮力,其大小等于物体所排开同体积流体的重量.”加上他们对浮力现象有生活上的经验(好在游泳时就能直接感觉到),因此从表面上看学生对浮力这个概念已有所了解,但我们进一步问这样一个问题,浮力是由什么产生 Students who have studied hydrostatics know that the Archimedean principle is: “The object immersed in the fluid (in whole or in part) is subjected to upward buoyancy, and its size is equal to the weight of the same volume of fluid displaced by the object.” They have a life experience with the buoyancy phenomenon (fortunately, they can feel it directly when swimming), so on the surface the students have already understood the concept of buoyancy, but we further ask such a question, what is the origin of buoyancy?
