因此 ，为了更准确地用粒子多重性来提取核耗散系数，选择一个低自旋的复合系统是重要的

Last through the equation analysis to philosophical plane, we found: This article does not negate the particles in the second, instead of a degree in physics in promoting the development of the basic conceptual material, spin with isospin,the two factor are the fundamental properties, quality and charges in a certain sense, there is a relationship.

最后通过这一关系式的分析，上升至哲学层面，我们发现：这篇文章并没有否定实物粒子的波粒二象性，反而一定程度上推动了物理学在物质基本概念上的发展，二旋性才是物质的根本属性，质量和电荷在一定意义上是有关系的，引力作用和电磁作用同属一种作用的不同侧面。

It is found that both scalar and vector potentials of neutron in theneutron rich nuclear matter become stronger although the isospin dependence is notstronger.

利用这样的耦合常数在RMF近似下计算的核物质的结合能与DBHF结果会有偏离，因而得到的核状态方程也会有偏离，如在饱和点处结合能有小于2％的偏差。

For the first time, we studied isospin effects on the two particle correlation functions, the light particle multiplicity and their ratio in HIC''s at intermediate energies, and find they are sensitive probes for the density dependence of the symmetry energy.

在国际上首次研究了重离子碰撞中两核子关联函数和轻粒子产生的多重性及比率的同位旋效应，发现它们敏感于核物质对称能的密度相关性。

For probing the isospin dependence of the medium correction of two-body cross sections, the results show that the behavior of the excitation function of stopping for medium size nuclear collisions can provide clearer information than that for heavier systems.

我们的结果还表明测量中等大小质量的系统在中能重离子碰撞中的核阻止本领激发函数比测量重的系统能提供更为确切的有关两体截面介质修正的信息。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
