核子学的研究虽可说在一九一九年刺得福特(Rutherford)已开其端,但直到一九三三年劳伦斯(Lawrence)等设计迴旋通以后才奠其基。在这短短的十五六年中,特别因这迴旋通和原子堆等新设备的贡献,产生了不可思议的结果。最顯著的是发见元素93 Neptunium(暂译作錼),元素94PlutoniuM(暂译作鐪),元素95 Americium和元素96 Curium(暂译作锯)。美国橡樹崗(OakRidge)原子能研究所的成绩,更足使人满意,发见了三十余种的新同位素和新元素。吾们在这里 Although the study of nuclear science can be said that in 1919 Rutherford had already opened its doors, it did not take shape until the design of Lawrence was revolt back in 1933. During this short period of fifteen six years, incredible results have been produced, in particular, from the contribution of new devices such as the spiraling and atomic stacks. The most prominent are the 93 Neptunium, the 94 PlutoniuM, the 95 Americium element and the 96 Curium. At the Oak Ridge Institute of Atomic Energy, the result was more satisfactory and saw more than thirty new isotopes and new elements. We are here
