摘　　要：18世纪末,法国化学家拉瓦锡预言石灰等土质不是简单物质。19世纪初,英国化学家戴维利用电化学技术从石灰中制得一种新的金属,并将其命名为“钙”(calcium),钙元素概念初步形成。随后,原子论的提出与钙原子量的测定使钙元素概念得到发展。到了20世纪,钙元素同位素的发现使人们对钙元素概念有了新的认识。总之,钙元素概念的发展史不仅是元素概念的发展史,也是科学思想、科学方法的演变史。At the end of the 18th century,French chemist Lavoisier predicted that soil material such as lime were not simple substances.In the early 19th century,the British chemist Davy used electrochemical technology to prepare a new metal from lime and named it"Calcium".The concept of calcium element was initially formed.Subsequently,with the advancement of the atom theory and the determination of the atomic weight of calcium,the concept of calcium had been developed.By the 20th century,the discovery of calcium isotope had given people a new understanding of the concept was calcium.In short,development history of calcium concept was not only the elements concept progressive process,but also the evolution history of scientific thought and scientific methods.
