独立二十年后,铀矿业已成为纳米比亚的经济支柱产业之一。中国核企虽然进入较晚,但已收获颇丰。1789年,德国化学家克拉普罗特从沥青矿中分离出来一种新元素,就用了1781年新发现的一个行星——天王星(Uranus)来命名它为铀(Uranium),元素符号定为U。1939年,又是德国科学家哈恩和斯特拉斯曼发现了铀的核裂变现象,铀成为核能军事应用关键的天然材料。自上个世纪50年代起,随着核电事 Twenty years after independence, uranium mining has become one of the economic pillar industries in Namibia. Although China’s nuclear industry entered a later stage, it has achieved great success. In 1789, the German chemist Klaprot separated a new element from the bitumen mine by using Uranus, a newly discovered planet in 1781, to name it uranium and the elemental symbol U . In 1939, another German scientist, Hahn and Strasman, discovered the fission of uranium, which became the key natural material for military applications of nuclear energy. Since the 1950s, with nuclear power
