摘　　要：通过对镉元素概念发展历程的考证分析可知,19世纪初,随着科学思想和化学分析方法的发展,德国化学家斯特罗迈耶首次通过药物分析制取并命名镉单质。至1826年,瑞典化学家贝采利乌斯首次测定镉原子量,赋予镉元素新的含义。镉原子量测定以及元素周期表形成,使镉元素的概念和镉原子结合起来。1924年,英国化学家阿斯顿通过质谱仪发现了镉同位素,从而形成了现代的镉元素概念。总之,随着科学思想和方法的不断发展,镉元素概念的内涵也在不断发展变化。According to the textual research and analysis of the development process of the concept of cadmium, at the beginning of the 19th century, with the development of scientific ideas and chemical analysis methods, German chemist Stromeyer first made and named cadmium through drug analysis. In 1826, Swedish chemist Bezelius measured the atomic mass of cadmium for the first time, giving cadmium a new meaning. The determination of the atomic mass of cadmium and the formation of the periodic table of elements combine the concept of cadmium and cadmium atoms. In 1924, British chemist Aston discovered cadmium isotopes through a mass spectrometer, forming the modern concept of cadmium. In short, with the continuous development of scientific ideas and methods, the connotation of the concept of cadmium is also constantly evolving and changing.
