大家知道,原子堆一方面可用于生产量较多的放射性同位素;另一方面它也能提供强大的中子源作中子物理与中子衍射等研究之用。回旋加速器可生产少量放射性同位素(特别是半衰期很短的)供研究用,但它的主要的用途是加速带电荷的粒子,并用它们来轰击原子核以产生核反应。物理学家通过核反应所引起的变化的观察,可以了解复杂的核结构问题。虽然,在上述一些研究中物理学家所起的作用最重要;但是,和平利用原子能的总计划的完成,同时需要化学家,数学家,冶金学家,工程师,生物学家,农艺学家与医学家等多方面的配合与共同努力。很早以前,化学家便在原 As we all know, atomic heap can be used on the one hand to produce more radioisotopes; on the other hand, it can also provide powerful neutron sources for neutron physics and neutron diffraction studies. Cyclotrons produce small amounts of radioisotopes (especially those with short half-lives) for research, but its primary use is to accelerate charged particles and use them to bomb the nuclei to create nuclear reactions. By observing the changes caused by nuclear reactions, physicists can understand complex nuclear structure problems. Although the role played by physicists is paramount in some of these studies, the completion of the master plan for the peaceful use of atomic energy requires the cooperation of chemists, mathematicians, metallurgists, engineers, biologists, agronomists and Medical scientists and many other cooperation and joint efforts. Long ago, the chemist was in the original
