原子核能 meaning in Chinese
nuclear energy
Examples
- The nuclei of atoms fuse, producing heavier nuclei and releasing nuclear energy, just as occurs in a hydrogen bomb .
原子核发生聚变，形成较重的原子核，并释放出原子核能，就象氢弹爆炸时所发生的情说那样。 - Many of the heaviest nuclei can be induced to break up into two fragments of intermediate size, a process called nuclear fission .
许多最重要的原子核能被诱发分裂为两块大小适中的碎片，这一过程称为核裂变。 - Fission and fusion, the sources of large-scale nuclear energy, deserve more than passing notice in a modern survey of physics .
裂变和聚变是大规模原子核能之源，在物理学的现代概观中值得注意而不是予以忽视。 - H . moreover , high density is required to increase the chance of collision . hence , the reactions can only take place in the core of the sun , with temperature over ten million degrees 10
首先核聚变需要极高的温度，让氢原子核能有足够的能量克服原子核之间的电排斥力，此外亦需要极高的密度去增加粒子碰撞的机会，所以核聚变只能在温度高达10
