贵刊1996年第1期刊登了王晓秋老师的《关于物体浮沉条件的探讨》一文(以下称原文);本文就物体的浮沉条件也谈一点看法,以求教于同行。1 原文认为“依密度的关系判断浮沉缺乏严密,对掌握基本概念造成混乱,不可以作为一般应用”。本文认为浮沉条件所指的物体密度应理解为物体的平均密度(即包含物体空心部分的密度)。因此,对于原文中上浮、下沉、悬浮三种情况,既可以依力
In the first issue of your publication, Wang Xiaoqiu published a article entitled “Study on the Conditions of Floating Objects” (hereinafter referred to as the original) by Wang Xiaoqiu in the first issue of 1996. This article also talks about the floating conditions of objects and seeks advice from their peers. 1 According to the original text, “The lack of strictness in the determination of floating density depends on the relationship of density and confusion over the mastery of basic concepts. It cannot be used as a general application.” This article believes that the density of objects under floating conditions should be understood as the average density of objects (that is, the density of the hollow part of the object). Therefore, for the three cases of floating, sinking and floating in the original text, it is possible to
