| 1. | An atom contains a tiny heavy nucleus .
一个原子含有一个微小而重的核。 |
| 2. | Heavier nucleus was believed to be formed of a number of protons and electrons packed closely together .
人们相信，较重的原子核是由若干个质子和电子紧密聚集在一起而形成的。 |
| 3. | 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。 |
| 4. | 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。 |
| 5. | " for his discovery of the fission of heavy nuclei
发现重核的裂变 |
| 6. | Particles , fission fragments , heavy nuclei
粒子裂变碎片重核 |
| 7. | From acs energies to rhic energies , heavier and heavier nucleus are accelerated and the beam energies become higher and higher
从gs能区到1c能区，被加速的核越来越重，束流能量越来越高。 |
| 8. | So , the dynamic behaviors of the liquid - gas phase transition in the systems from the 40ca to the super - heavy nuclei 298114 have been studied systematically
而为了得到比较合理的、一系列的基态原子核的性质，我们则是使用了相对论平均场。 |
| 9. | Nowever this may imply that the errraticity method is sensitive to the appearance of novel physics in the central collosion of heavy nuclei
尽管如此，这个事实另一方面也意味着事件阶乘矩的erraticity分析可能对重核碰撞中出现的新物理很敏感。 |
| 10. | Moreover , the calculations of the valence neutrons for the single - particle states of 49ca and 209pb show that the neutron halos or skins can exist in the region of heavy nuclei
对49ca和209pb各单粒子激发态外层中子的计算表明：在中重和重核区存在中子晕、皮核。 |
