“摩尔”这个概念并不难理解,在国际单位制中给它下了很明确的定义。难以理解的是“物质的量”这个物理量,所以要树立摩尔的概念,搞清楚“物质的量”的涵义是个关键问题。 “物质的量”和“长度”、“质量”等物理量一样,也是基本的物理量,由于它的问世较晚,又由于“物质的量这个词作为科学名词,从结构和用字上都不够理想,在第十三届国际计量大会 The concept of “Moore” is not difficult to understand. It is clearly defined in the International System of Units. It is difficult to understand the “physical quantity” as the physical quantity. Therefore, to establish the concept of Moore, it is a key issue to understand the meaning of “quantity of matter”. “Substance quantity” is the same as physical quantity such as “length” and “quality”, and it is also a basic physical quantity. Because it came out later, and because the term “substance quantity” is a scientific term, it is not ideal from the point of structure and character. , at the 13th International Conference on Metrology
