1921年诺贝尔化学奖获得者——索迪

Frederick Soddy——Winner of the Nobel Prize in Chemistry in 1921

在探索微观元素的过程中,同位素与放射性元素位移定律的发现无疑具有里程碑式的意义。同位素的发现修正了道尔顿原子学说,元素位移规律的发现使放射化学成为一门独立的学科,为此1921年的诺贝尔化学奖授予了同位素与元素位移定律的发现者—弗雷德里克.索迪,2011年恰逢索迪逝世55周年,特写此文来纪念他对现代放射化学与核物理学做出的贡献。

The discovery of isotopes and radioactive elements displacement law is a landmark in the process of exploring the microelements. The discovery of isotopes revised the Dalton＇ s atomic theory. The discovery of the elements displacement law made the radiochemistry to become an independent subject. Therefore,the Nobel Prize in Chemistry in 1921 was awarded to Frederick Soddy for his contribution in discovering isotopes and presenting elements displacement law. 2011 is the 55th anniversary of Soddy＇s death. So,we write this paper in memory of his contributions to the modern radiochemistry and the nuclear physics.
