原子核

The theoretical prediction of large energy gap exists near the neutron number~44 and proton number~38-40 are also compared and discussed.

许多理论预测在中子数N~44，而质子数Z~38-40 附近，存在大的能隙，而我们研究的几个原子核，其核子数恰好位在此能隙附近，所以文中也针对此变形位障所预测的幻数加以讨论。

By systematically analyzing the single particle level and the occupation probability near the Fermi surface,and the rule of nuclear particle number deviations with proton numbers for N =8,20,28,50,82,126 neutron chains within the relativistic mean-field model with BCS theory,we have discussed the stability of the shell structure for the traditional neutron magic in the whole range of nuclear spectrum from neutron line to proton line,and predicted that traditional neutron magic number effect shall possibly disappear only in light neutron-rich nuclei.

在考虑了BCS理论的相对论平均场模型框架内，通过系统研究 N =8，20，28，50，82和126六条同中子素链中每个元素费米面附近的单粒子能级间隔、粒子数占有概率比以及原子核体系的粒子数偏离随质子数的变化规律，讨论了传统中子幻数的壳结构在从中子滴线区到质子滴线区整个核谱上的稳定性，预言只有在轻核的丰中子区域，传统的中子幻数效应才可能消失，并把计算结果和最近的文献报道作了比较。

However, it is possible that the two stars are neutron stars and we can imagine that they are two huge nuclei.

但是，如果是两颗中子星，我们可以把它想象成是两个巨大的原子核。

We thought of a nucleus as make up of neutron and proton.

我们认为原子核是由中子和质子构成的。

Theoretical predict is given, that electron density of inner shell at nuclear surface decreases and energy level also decreases with increasing of charge state, nuclear lifetime increases slightly with previous reason but increases with a jump when energy level drops to a critical value.

理论预言了随着电荷态的增加，内壳的电子在核表面的电子密度降低，内壳电子能级也降低，不稳定原子核的寿命由于前一原因而缓慢增加，但当内壳电子能级降到特殊能量时产生剧烈增加。

Nuclear size effects are intertwined with nuclear force effects.

原子核大小的影响与核力的影响纠缠在一起。

The first study of the strong interaction is nuclear between the nuclear force, it is to make the role of nuclear together to form nuclei.

最早研究的强相互作用是核子之间的核力，它是使核子结合成原子核的作用。

The nuclear force can maintain the stability of a nuclei so that it can also maintain the stability of the neutron stars.

这种短程力能使原子核保持稳定，当然也能使带电中子星保持稳定。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
