补充资料：氚
| 氚 tritium 元素氢的一种放射性同位素 。符号  ，简写为3H，氚还有其专用符号T。又称超重氢。氚的质量数为3，在天然氢中，氚的含量为1×10-15％。1934年，英国E.卢瑟福等人在加速器上用加速的氘核轰击氘靶，通过核反应发现氚，美国W.W.洛齐尔等证实重水中存在氚，1939年美国L.W.阿耳瓦雷等证明氚有放射性。自然界的氚是宇宙射线与上层大气间作用，通过核反应生成的。氚的性质与氢很相似。
利用反应堆的中子，采用氟化锂、碳酸锂或锂镁合金做靶材，能大量生产氚： Li＋n →4He＋3H然后利用热扩散法，使氚富集至99％以上。氚主要用于热核武器、科学研究中的标记化合物，还可能成为热核聚变反应的原料。 |
