Relative isotopic mass,英文定义如下: The relative isotopic mass of an atom is the ratio of its atomic mass to the atomic mass of a reference isotope of the same element. It is used to account for the different masses of atoms that have different isotopes....
他说「同一种元素的原子有相同的重量(weight)，不同元素的原子有不同的重量。」因此atomic weight在中文里翻译成了「原子量」。但是当时由于重量和质量(mass)是相同的概念，因此虽然实际中获得的都是原子的相对质量，但仍然称作原子量。 20世纪初，物理学家采用质谱技术测量原子质量，使用了在物理学上比...
