查询词典 hyperons

The Furnstahl-Serot-Tang model, which is extended by including hyperons into normal hadronic matter, is utilized to study the properties of strange hadronic matter.

这个模型在普通强子物质中再引入$\Lambda$，$\Xi$超子及它们之间的相互作用。

We assume the core of neutron stars is a β-stable strange matter consisting of nucleons and hyperons, then the influences of the hyperon-hyperon interaction on the properties of neutron stars are studied in the relativistic mean-field approximation.

我们假定中子星内部物质是由核子与超子混合组成的β稳定的奇异强子物质，在相对论平均场框架内研究了超子超子相互作用对中子星性质的影响。

But because difference among the predictions of different theoritical models in low z region is small, it is hard to tell us which model is more compatible with the experimental result. Our results from high z binning show a good consistence with the predictions based on z-dependence SU (3) asymmetry, quark-Diquark and pQCD model, which indicate the ud quarks in Λ hyperons provide contributions as well as s quark and the contribution is the function of z.

高z区间分法下归一法和螺旋度平衡法的分析结果显示同z依赖的SU（3）对称模型、夸克--反夸克模型和pQCD模型预言的纵向自旋转移值S〓和z的关系较一致，从而表明Λ超子中u夸克不但对Λ的极化有贡献，而且其贡献和Λ携带的能量份额z有关系。

The Oppenheimer-Volkoff mass limits of neutron stars calculated from different equation of state are 1.52-2.06M(subscript ⊙), and the radii are 10.24-11.38km with hyperons included.

对于中子星，考虑超子后不同参数组给出的质量极限的范围为1.52-2.06M，半径为10.24-11.38km。

The universal transverse polarization phenomcna for inclusively produced hyperons haveeluded the successful quantum chromodynamicsdescription in the past decades.Inthis thesis,we report their QCD-motivated factorization approach.

高能强子碰撞过程中单举产生超子的横极化现象一直缺乏成功的量子色动力学描述针对这一问题本文中给出了一个量子色动力。。。

The various effective interactions'(including DDME1,TW99,NL2,TM1,TM2,GL85 and GL97) influence on the constitute, equation of state and mass of neutron star are studied in the framework of relativistic mean field theory considering the interacting nucleons, hyperons and mesons system at finite temperature (T=20 MeV).

从相对论平均场（Relativistic Mean Field，RMF）理论出发，考虑核子、超子和介子的相互作用，研究了一定温度（T=20 MeV）下，各种不同相互作用参数组（DDME1、TW99、NL2、TM1、TM2、GL85和GL97）对中子星物质的粒子组成、状态方程和质量等的影响。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
