2.重子数。
| | | baryon: n. 【核物理学】重子。 | | number: n. 1.数；数字；〔pl.〕算术。 2.(汽车等的)号 ... | |
| a number equal to the difference between the number of baryons and the number of antibaryons in any subatomic structure; it is conserved in all types of particle interactions
|
| In particle physics, the baryon number is an approximate conserved quantum number of a system. It is defined as |
例句与用法 | 1. | Baryon number transport and stopping provide entirely different initial condition for the probably produced qgp
中心快度区的重于数阻止和重子数穿透的倩况为可能产生的qgp提供了完全不同的初始条件。
| | 2. | The following phenomenon is desired to seen : with the increase of colliding energy , the net baryon number tends to be zero in the mid - rapidity region
人们渴望在高能重离子碰撞中看到：随着对撞能量的升高，在反应的中心快度区出现净重于为零的现象。
| | 3. | The experimental results become close to entire baryon number transport step by step , from the entire baryon number stopping at low - energy to baryon transport with energy increasing
实验上，从低能时中心快度区的完全重子数阻止，到能量逐步升高时，开始出现重子穿过。
| | 4. | The results show that the chiral symmetry is restored partially when the strange matter density increases and 2 plays a very important role in the strange matter which may approach the constituents of the neutron stars . in additions , we can find that the strange matter density where the - condensate emerges is led to the ratio of the nucleon number to baryon number . and the occurrence of - condensate is only in certain density and gradually increases for higher density , so we guess that - field may be necessary to carefully consider for studying the neutron stars
( 3 ) -凝聚出现时所对应的奇异物质密度值与核子在奇异物质中的比例有关。另外，虽然本文对夸克凝聚的讨论是在低密度的奇异物质中进行的，但是-凝聚的出现却需达到一定的密度值并且随密度的增大而递增，所以我们推测场可能对于仔细研究中子星是一必要因素。
| | 5. | There has been many papers to discuss the in - medium quark and gluon condensates in nuclear matter which use the models with su ( 2 ) l su ( 2 ) r sym - metry . now , we make use of the chiral model su ( 3 ) l su ( 3 ) n including the baryon octet to discuss the quark condensate < qq > in strange matter , where q is an up or down quark field . on the one hand , from the experimetal data , it is found that < qq > vac = - ( 225 25mev ) 3 , on the other hand , with the hellmann - feynman theorem , quark condensate can be evaluated on the hadronic level . in this paper , we will investigate the quark condensate in strange matter with the chiral symmetry su ( 3 ) l x su ( 3 ) rspontaneous breaking lagrangian to obtain the variation of the quark condensate in the strange matter when the baryon number change . it can be applied to understand the neutron stars when the neutron star are considered to be constructed by the strange matter . because nertron stars are homogeneous and at very low temperature , we will use the mean - field approximation and zero temperature throughout this paper
鉴于已有大量文献讨论了核物质中的夸克凝聚，本文将讨论在奇异物质中的夸克凝聚。而在介质中的夸克凝聚的基本公式可由hellmann - feynman理论导出，所以运用手征对称自发破缺拉氏量以及平均场近似，我们就可以讨论在奇异物质中的夸克凝聚，由所计算的结果表明： ( 1 )奇异物质中的夸克凝聚随奇异物质密度的增大而单调减小。 ( 2 ) -凝聚的出现对衰减率有影响。
