物质的量是表示微观粒子多少的物理量,它架起了宏观世界与微观世界的桥梁.而物质的量这一基本物理量的形成,离不开阿伏加德罗常数,如同长度的衡量离不开其单位“米”一样,不然中国历史上秦始皇统一度量衡就失去其历史价值.加强对阿伏加德罗常数的认识,将更有利于理解物质的量这一物理量的深刻内涵.所以我们说,阿伏加德罗常数是建立物质的量这一桥梁的“引桥”.
The amount of matter is the physical quantity representing the number of microscopic particles. It sets up a bridge between the macroscopic world and the microscopic world. The formation of the basic physical quantity of the amount of matter is inseparable from the Avogadro constants, just as the measurement of the length cannot be separated. Its unit is “M”, otherwise Chinese history will lose its historical value in the unified measure of the Qin Shi Huang. To strengthen the understanding of Avogadro’s constant will be more conducive to the understanding of the profound connotation of the physical quantity of matter. So we say, Avogadro’s constant is the “bridge” for establishing the bridge of matter.
