为了检查学生运用所学物理知识,灵活地解决实际问题的能力,在今年我市初中升学考试物理试题中,我们编写了一道有关运用土比重计测液体比重的试题。此题解法较多,思路各异。现将常见的几种解法作扼要介绍。原题:要想测定某种液体的比重,但没有比重计,于是用一根粗细均匀的木棒,下 In order to check the students’ ability to use the physics knowledge they learned and to solve practical problems flexibly, in this year’s physics examination questions for the junior high school entrance examination in our city, we wrote a question about using the proportion of soil to measure the proportion of liquids. There are many solutions to this problem and they have different ideas. Several common solutions are briefly introduced. The original title: To determine the specific gravity of a liquid, but without a pycnometer, use a thick, uniform wooden rod.
