核子

Among mesons, the lightest and most important one is certainly the pion, thus it is no accident that its structure, properties (both in free space and in nuclear matter) and interactions with nucleons and nuclei have gotten considerable attentions in the past and again at the present time.

在各种介子中，π介子是最轻且最重要的介子，关于自由空间中π介子的结构与性质、核介质内π介子的性质、π-核子相互作用与π-核相互作用等问题，始终受到相当多的关注。

He has made systematic high-level research achievements in the study of solar nebular evolution, meteorites, cosmic dust and Apollo lunar rocks, as well as comparative planetology, the climatic and environmental change of, and mass extinction induced by the impact of extraterrestrial bodies on the earth, formation and evolution histories of solar system, two-stage accretion model of earth's origin, original inhomogeneity of the primordial earth and its constraint on metallogeneity and tectonic evolution.

其地下核子试验地质效应综合研究於1978年获全国科学大会奖；吉林陨石综合研究於1986年获中国科学院重大科技成果一等奖和1987年全国自然科学三等奖；《天体化学》专著於1991年获中国科学院自然科学一等奖；月球探测成果更获工业与资讯化部特等奖和国防科工委个人突出贡献奖。欧阳自远院士在国内外已发表专著16部、主编著作14部、论文426篇，培养硕士、博士与博士后65人。

He was known as the "father" of nuclear physics, pioneered the orbital theory of the atom, notably in his discovery of rutherford scattering off the nucleus with the gold foil e XP eriment.

他被称为"核物理学之父"，是原子轨函数说的先驱，最著名的成就是利用金箔试验分离出了核子。1908年，他被授予诺贝尔化学奖。

This paper expounds the conception of the compactness, introduces some methods for detecting the field compactness such as the sand cone method, the cutting ring method, the nuclear magnetometer method, and the core-drilling method , etc.

阐述了压实度的概念，介绍了灌砂法、环刀法、核子仪法、钻芯法等现场压实度的检测方法，指明了各种检测方法适用范围、注意事项，为施工现场压实度的有效控制提供了借鉴。

We mainly investigate the influence of different covariant representations on the satisfiable extent of the Hugenholtz-Van Hove theorem in the nuclear medium in the framework of DBHF.

结果表明：不同的协变表示对核子自能各分量的动量相关性和密度依赖性均有重要影响，进而对核介质中HVH定理的满足程度产生重要影响。

This would only lead to a repeat of the kind of leadership humanity already experiences that are self-serving in nature.

正是这类自私自利的领导阶层一次又一次地带来如此极端的冲突而结果导致了最终的核子歼灭。

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）。
