在高中的单位制的学习中,出现了很多让我们困惑的地方,比如有的资料上认为“厘米”“克”等单位不是国际单位,有的资料上认为是国际单位,各种资料的解析不是特别明确,现将在高中涉及到的“基本量”“基本单位”“国际单位”“国际单位的基本单位”等几个概念进行辨析.一、基本量、基本单位和导出单位物理量是用来定量描述物理现象的,它可以分为很多类.第一类:凡是可以相互比较的量,如距离、高度、位移、波长等等都是同类的量,可以选出某一特定
In the study of the high school’s system of units, there were many places that made us confused. For example, some sources hold that the units such as “cm” and “g” are not international units and that some sources regard them as international units. The analysis of data is not particularly clear, and will now be analyzed in several concepts such as “basic quantity”, “basic unit”, “basic unit of international unit”, “basic unit of international unit” , Basic quantity, basic unit and exporting unit Physical quantity is used to quantitatively describe the physical phenomenon, it can be divided into many categories. The first category: any amount can be compared with each other, such as distance, height, displacement, wavelength, etc. are similar The amount of choice of a particular
