放射性蜕变 radioactive transformation
- 粒子是从天然放射性蜕变得到的带正电的氦核。
Alpha particles are positively charged helium nuclei obtained from natural radioactive decay. - 放射性元素的自发性蜕变被发现后,路德·福特勋爵首先在人工蜕变研究方面取得了成就。
After the discovery of the spontaneous transmutations of radio-elements, the achievement of the first artificial transmutations is due to Lord Rutherford.
