每日一词：核裂变与核聚变揭示了两种能量释放机制。在核裂变中，如铀-235的案例，当一个大原子核分裂成两个较小的核，如铷和铯，多余的质量以核结合能的形式转化为能量。这个过程在核电站中被利用，比如远古时期加蓬奥克洛的自然核裂变现象。相反，核聚变则是轻原子核合并的过程，如在太阳核心，氢原...
Nuclear fusion is the opposite process, in which two light nuclei merge to form a heavier one, yielding energy because the combination is lighter than the sum of its parts. Atoms heavier than iron can undergo fission, while lighter ones can fuse. Nuclear power stations generate energy from ...

NUCLEAR BINDING ENERGY, FISSION AND FUSION (2024-2047)YungKuo Lim
nuclear fission:核裂变，又称核分裂，是指由重的原子核，主要是指铀核或钚核，分裂成两个或多个质量较小的原子的一种核反应形式。原子弹、裂变核电站或核能发电厂的能量来源就是核裂变。其中铀裂变在核电厂最常见，热中子轰击铀235原子后会放出2到4个中子，中子再去撞击其它铀235原子，从而形成链式...

The declining reserves of fossil fuels and their detrimental effects on the environment have thrust nuclear power based on fission reaction into the limelight as a promising option to energy-starved economies around the world. However, the 1986 Chernobyl

An example of fission implementation is highlighted, referring to the Czech Republic legislation; an example of application in fusion technology is the implementation of the Nuclear Safety Culture in the ITER project, located in Cadarache, in the south of France. The aim of the paper is to high...
heavier than iron absorbs energy. The opposite is true for the reverse process, nuclear fission. This means that fusion generally occurs for lighter elements only, and likewise, that fission normally occurs only for heavier elements. There are extreme astrophysical 天体物理学 events that can lead ...
