使用托盘天平测物体质量,除课本上介绍的知识外,还要注意以下两点:一、天平的“秤量”及“感量”对于每一架天平,上面都有一个铭牌,标有天平的型号、产地、生产日期、天平的“秤量”和“感量”.所谓“秤量”,是指天平所能测量的最大质量数,“感量”是指天平所能测量的最小质量数。知道了一架天平的“秤量”及“感量”,就可以知道天平的测量范围了.比如实验室常用的学生天平秤量是200g,感量
Using tray balance to measure the quality of objects, in addition to the knowledge introduced in the textbook, we should also pay attention to the following two points: First, the scale’s “weighing” and “fluence” For each balance, there is a nameplate on the scale, marked with a balance Model, origin, production date, scale’s “weighing” and “influence.” The so-called “weighing” refers to the maximum mass that the balance can measure, and “flux” refers to the smallest mass that the balance can measure. Knowing the scale’s “weighing” and “fluence”, you can know the measuring range of the balance. For example, the scale of a student’s common balance in a laboratory is 200g.
