This interaction creates a huge burst of energy that is still burning at the heart of stars all across the universe. Unlike fission, nuclear fusion also has the added benefit of being self-sustaining without creating harmful waste. However, achieving and controlling fusion has been a lot more...
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...
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 fis...
1.Nuclear energy must be a consideration for the future with the rapidly depleting supply of fossil fuels. This type of energy can be created through nuclear fission and nuclear fusion. Nuclear fission is the splitting of a heavy atom into two or more parts, releasing huge amounts of energy....
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...
When the nuclei are merged, the excess energy is released. Like fission, nuclear fusion can also transmute one element into another. For example, hydrogen nuclei fuse in stars to form the elementhelium. Fusion is also used to force together atomic nuclei to form the newest elements on the pe...
This chapter discusses nuclear fission, nuclear fusion, and geothermal energy in detail. Nuclear energy comes from energy incorporated in atomic nuclei at the time when they are born; it is used to hold them together called binding energy. Of the nuclei of the periodic table, those at the ...
Fission and fusion are two words that sound very much alike, but they're actually very different! In this lesson, find out what each one is and how they work to create nuclear energy. Create an account Table of Contents Atoms and Molecules Nuclear Fusion Nuclear Fission Fusion and Fission...
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 fusion of light elements, such as deuterium (2H) and tritium (3H), releases an energy per nucleon (MeV/u) or energy per unit of material considerably greater than can be achieved by nuclear fission. Thermonuclear fusion requires energy to reach high temperatures and maintain nuclear plasma...
