原子核的

Nuclear sizes are important bulk properties of an atomic nucleus.

原子核的大小是原子核的最基本性质之一。

Upon discovering basic properties of the atomic nucleus, scientists found a way to release a huge amount of energy in nuclear reactions.

The energy equivalent of the mass discrepancy in a nucleus is called binding energy.

与原子核中的质量差相对应的能量叫做原子核的结合能。

Radioactive decay studies have found a kinds of elements can be α or β decay and the decay into another element, while the α-decay product of -α-rays became one of the deep structure of the material means of .1911, the Rutherford and others bombarded atoms with α-rays observed wide-angle deflection to determine the nuclear structure of atoms and nuclei was first proposed the term .1919 year, Rutherford and others have also found that with α-ray bombardment of nitrogen will release the nuclear protons, this is the first time Artificial realization of a nuclear reaction, after the bombardment of nuclei with the radiation caused by nuclear reaction method to become the primary means of research in nuclear.

放射性衰变研究发现了一种元素可以通过α衰变或β衰变而变成另外一种元素，而α衰变的产物——α射线又成了人们探讨物质深层结构的手段。1911年，卢瑟福等人用α射线轰击原子、观察到大角度偏折，从而确定了原子的有核结构，并首次提出原子核这一名词。1919年，卢瑟福等人又发现用α射线轰击氮核会放出质子，这是首次用人工实现的核反应，以后用射线轰击原子核来引起核反应的方法逐渐成为研究原子核的主要手段。

A vivid example of this: in the two deuterium nuclei polymerization into a helium-4 nucleus, it seems quality is not conservation, is the quality of helium-4 nucleus does not mean that two of the deuteron and quality.

这个例子生动地说明：在2个氘原子核聚合成1个氦4原子核时，似乎质量并不守恒，也就是氦4原子核的质量并不等于2个氘核质量之和。

Basing on the view point of the α particle structure of the 12 c nucleus,the form factor and the transition form factor of the α particle in 12 c nucleus are as inputs,the inelastic scattering of pion-12c for 2+(4.43 mev) and 3-(9.64 mev) at tπ=150,180 mev are studied within glauber scattering theory.the calculated differential cross sections show better agreement with the experimental data.

从12c原子核的α粒子结构观点出发，应用12c原子核内α粒子的形状因子和跃迁形状因子，在glauber散射理论框架下，计算了共振区内能量为tπ=150，180 mev，π-12c的2+(4.43 mev)和3-(9.64 mev)非弹性散射微分截面。理论结果与实验较好8 t tt 8.c o m 地符合。

Outside the atom the electron cloud has the track, according to leaves nucleus far or near differently, these orbits are divided into several levels, the more lower energy level the more near to nuclear.

原子外面的电子云运行是有轨道的，按照离原子核的远近不同，这些轨道被分为几层，离原子核越近能级越低。

C. excitation energy of the nucleus, excitation energy of the neutron, and kinetic energy of the

C。 原子核的激动能，中子的激动能，和原子核的动能

From Nucleons to Nucleus deals with single-particle and collective features of spherical nuclei.

从核子到原子核处理球形的原子核的单个粒子和集体特征。

This agreement confirms that nuclear short range correlation seems to be important and sets up a theoretical basis for calculating nuclear halo-like phenomena which may originate from the short range correlation between nucleons in a halo-like nucleus.

表明：原子核中核子间的短程关联是重要的，它可能是原子核晕核结构现象的动力学起源，为理论上研究原子核的晕现象打下了基础。

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％。
