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...
Atoms heavier than iron can undergo fission, while lighter ones can fuse. Nuclear power stations generate energy from fission reactions. About 2 billion years ago, natural fission took place at Oklo in Gabon, Africa, when groundwater concentrated uranium deposits. Fusion occurs in the Sun's ...
NUCLEAR ENERGY : FISSION AND FUSIONClinton, President Bill
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...
Nuclear Fission and FusionChang Caixiang
Nuclear fission and fusion reactions 能源是人类生活中必不可少的一部分,但随着人类对能源需求的不断增长,且很多传统能源来源已经面临耗竭的局面,新能源的研究和开发变得日益重要。其中,核能作为一种高效、稳定的能源源占据了重要的地位。本文将从核裂变和核聚变两个方面介绍核能的来源和应用。

The fission fragment anisotropies rise rapidly as the beam energy decreases through the barrier region. This is interpreted as showing that collisions with the tips of the deformed target nucleus lead to quasifission, collisions with the sides to fusion-fission.关键词:...

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
