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 a nuclear reaction in which two or more atomic nuclei collide at very high speed and join to form a new type of atomic nucleus (e. g. The energy that the Sun emits into space is produced by nuclear reactions that happen in its core due to the collision of hydrogen ...
nuclear fusion:核聚变(nuclear fusion),又称核融合、融合反应、聚变反应或热核反应[1] 核是指由质量小的原子,主要是指氘或氚,在一定条件下(如超高温和高压),只有在极高的温度和压力下才能让核外电子摆脱原子核的束缚,让两个原子核能够互相吸引而碰撞到一起,发生原子核互相聚合作用,生成...
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 fusion or nuclear fissionWILHELMS,WALTER
Nuclear fusion is the process in which two nuclei of an atom combine together at high temperature to form different atomic nuclei. For example, hydrogen combines together to form helium. This is how the sun and stars get power to lighten up. Fusion occurs...
解析 what is the difference between fission and fusion?Do today's nuclear power plants utilize fission or fusion?聚变和裂变的区别是什么?当今核电厂用的是裂变还是聚变?ANSWER:1 In general,fission is the separ... 分析总结。 当今核电厂用的是裂变还是聚变...
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:...
This chapter reviews the history of nuclear fusion, and states how in the 20th century it became possible to split an atom through nuclear fission, or combine them together using nuclear fusion. Only in the early 20th century was it realized that nuclear fusion is the energy source that runs...
