nucleon number meaning in English

核子数，质量数
质量数

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。
