| 中文摘要: |
| 1869年，门捷列夫在第一张元素周期表中的锆元素后留出原子量为180的元素位置，预测铪与锆同族。1913年，原子序数和X射线光谱定律的提出为铪元素的鉴定提供了理论基础。20世纪20年代，玻尔理论的发展促进铪元素假说的形成。1923年，赫维西和科斯特借助X射线光谱技术发现铪元素。20世纪30年代以后，同位素理论和质谱技术促成了铪同位素的发现，使人们对铪元素有了新的认识。总之，铪元素及其同位素的发现是技术进步和思想发展的共同结晶。 |
| 英文摘要: |
| In 1869, Mendeleev set aside an element position with atomic weight of 180 after zirconium in the first periodic table, and predicted that hafnium and zirconium were of the same family. In 1913, the law of atomic number and X-ray spectrum provided theoretical basis for the identification of hafnium. In the 1920s, the development of Bohr"s theory promoted the formation of hafnium hypothesis. In 1923, Hevesy and Coster discovered hafnium by X-ray spectroscopy. After the 1930s, isotope theory and mass spectrometry technology contributed to the discovery of hafnium isotopes, which made people have a new understanding of hafnium. In short, the discovery of hafnium and its isotopes is the common crystallization of technological progress and ideological development. |
