“等效替代法”是一种研究物理问题的思想方法,也是一种解决物理问题的有效手段.学会运用这种方法,能够拓宽同学们的解题思路.下面谈谈这种方法在解限定器材测物质密度实验题中的应用.一、等体积例1给你一台已调节好的天平(带砝码)和一个盛满水的烧杯,只用这些器材(不使用任何 “Equivalent substitution method” is an ideological method for studying physics problems, and it is also an effective means for solving physical problems. Learning to use this method can broaden the students’ problem solving ideas. Let’s talk about this method in the definition of solutions. The application of the instrument to measure the density of matter in the test item. 1. An equal volume of Example 1 gives you a regulated balance (with weights) and a beaker filled with water. Use only these devices (do not use any
