原子核的

The classical analog of this state of motion is a straight-line trajectory back and forth through the nucleus.

这个运动状态的经典对应，是通过原子核来回运动的直线轨道。

This new microscopic description makes it possible to construct various configurations and to trace them as a function of rotational frequency or nuclear shape.

但它对于物理问题的描述有如下局限性：核子间的对关联没有被包括在内；对原子核系统外加轴和旋称对称性限制。

Therefore, one has to use some kind of truncation scheme.

原子核配对壳模型就是基于以上的考虑而提出的。

This nucleus is composed of positively charged protons , and electrically uncharged neutrons .

原子核中包括带正电的质子，和未带电的中子。

Atomic nuclei consist of combinations of protons, or positively-charged particles, and neutrons, or uncharged particles.

原子核是由质子与种子相结合而构成；之子也叫带正电荷的粒子，中子也叫不带电荷的粒子。

Be able to ionization happened in molecule or atom in atmosphere under machinery , brightness , static electricity , chemistry or biological energy source effect, whose outer layer electron abjunction atomic nucleus, these lose the electronic molecule or the atom is called the positive ion or the positive ion with positive charge , us.

大气中的分子或原子在机械、光、静电、化学或生物能作用下能够发生电离，其外层电子脱离原子核，这些失去电子的分子或原子带有正电荷，我们称为正离子或阳离子。

The researchers fired a beam of calcium ions, each containing 20 protons, into a target of californium, a highly radioactive synthetic substance with 98 protons.

他们轰击了一束每个原子中含有20个质子的钙离子，得到了锎，一种原子核中含有98个质子的更高级人造放射性元素。

Every nucleus lives in splendid isolation, shielded from the rest of the world by its own encircling electrons.

绕核旋转的电子都使每个原子核同世界的其余部分屏蔽开来。

Computation makes clear as a result, the smooth balance of power that 6 ammonia in 6 ammonia magnesium chloride form in nucleus and other electron breaks up in field, cent is two class, the first class 4 ammonia, the 2nd class 2 ammonia, when outside ambient changes, it is to shuck off 4 ammonia element likely most, additionally 2 ammonia are shucked off again after warming up, this one conclusion accords with experimental result to agree.

计算结果表明，六氨氯化镁中的6个氨在原子核和其它电子形成的平均势场中分裂，分为两级，第一级4个氨，第二级2个氨，当外界条件变化时，最有可能是脱去4个氨分子，升温后再脱去另外2个氨，这一结论符合实验结果一致。

An atom is made up of a nucleus and some electrons surrounding it.

原子是由原子核和它周围的电子组成的。

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）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
