欧阳自远院士，地球化学与天体化学家。1935年出生於江西吉安，1956年毕业於北京地质学院，1960年中国科学院地质研究所研究生毕业。1960至1966年在中国科学院地质研究所从事核子地质、陨石学和天体化学研究；1964至1978年，负责中国首次地下核子试验选场、模拟实验与地质综合研究。

In the relativistic σ-ω model, the influence of the parameters in self-interaction of σ meson to the equation of state of normal nuclear matter, especially, to incompressibility, effective mass, and coupling constants, is studied in detail. We find that these parameters have an intense relationship to the property of nuclear matter.

在相对论σ-ω模型里，详细讨论了σ介子的自相互作用参数对正常核物质物态方程的影响，特别是对核物质的不可压缩系数、有效质量，以及σ介子与核子、ω介子与核子之间的耦合常数的影响，发现这些参数与核物质的性质之间有紧密的联系。

While probably larger than North Korea's one kiloton test in 2006, experts say it does not appear to represent a major technical advance.

不过专家说，北韩第二次核子试验虽然可能规模大於 2006 年当量 1 千吨的首次核子试验，但是看来并没有显示出重大的技术进步。

As the bombarding energy rises up to 30-100 MeV/u, the nucleon-nucleoncollision begins to play an important role.

当能量继续升高至30—100MeV／u以上，核子—核子的碰撞作用开始起较大的影响。

It was found that the effect of the Dirac states could not be neglected, especially in the case of giant monopole resonance.

同时也讨论了自洽条件下Dirac海核子态的作用，指出Dirac海核子态的贡献不能忽略，特别是在核的巨单极共振的情况。

Our purpose is to try to understand some long-standingproblems in light baryon which include (1) The energy level or-der between the positive- and negative- parity partner states,in particular, Roper resonance puzzle;(2)The baryon spin-orbitstructure puzzle-the absence of spin-orbit effects in baryon spec-trum;(3)The calculated amplitudes of nucleon form factors droptoo fast and the uncertainty of the multipole strength in thetransition process of rN →△.

我们的目的是试图解决以往组分夸克模型在轻重子系统的研究中存在的几个问题：(1)重子谱中正负宇称配对态的能级次序，特别是Roper共振之谜；(2)重子谱中自旋轨道看不见之谜；(3)核子形状因子随转移动量增大而下降过快及核子到其共振态光和电生过程中多极子强度和形状因子的不确定性。

The ground states properties of Ne-isotopes were calculated with Relativistic mean field theory. Compared with the experimental datas, its discovered that the nucleus properties chang regularly with the changes of neutron number when the proton number is even. The results proved indirectly that even nucleus has no direct influenced on another kind of nucleus. Besides, the applicability of Relativistic mean field theory in this region was tested.

用相对论平均场理论计算了Ne同位素的基态性质，并和实验比较，发现当质子是偶数时，核的性质有规律地随中子数的变化而变化，由此间接证明了偶数核子对另一类核子无直接影响；同时，也检验了相对论平均场理论在该区域的适用性。

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。

Article 38 Nuclear reactor operator means a person who operates or directs others to operate the control of a nuclear reactor.

第38条凡操纵或指挥他人操纵核子反应器控制装置者为核子反应器运转转人员，分运转员及高级运转员两种，其操作范围依左列规定

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
