Meanwhile we find that decay constant fn and the tt mass mv monotonously decrease as nuclear matter density increases 我们同时发现介子的衰变常数f _和质量m _随着核物质密度_ n的增加而单调递减。
Here by applying qhd - i model and zm model , we have mainly discussed the effective nucleon mass in hot and dense nuclear matter 本文主要采用( qhd - )模型和zm模型，讨论了在热密核物质中核子有效质量的变化规律。
The result is consistent with the usual assumption that the chiral symmetry is gradually restored as density of a nuclear matter increases 这个结果和手征对称性随着核物质密度增加而逐渐恢复这一通常假设是符合的。
In prokaryotes the nuclear material is simply a circular strand of dna , not complexed with histone proteins , and cell division is amitotic 在原核生物中，核物质仅是一个简单的环状dna ，而不与组蛋白结合，并且细胞为无丝分裂。
Standard test method for non - destructive assay of nuclear material in waste by passive and active neutron counting using a differential die - away system 用差动衰减系统钝化-活化中子计数法对废物中的核物质进行无损分析的标准试验方法
They are scheduled to visit a five - megawatt reactor , a nuclear fuel fabrication plant and a reprocessing plant in the yongbyon nuclear complex 他们计划访问宁边核物质合成厂的一个五兆瓦特反应堆，一个核燃料加工厂，和一个核燃料再处理厂。
Using the effective action we got in a nuclear matter , we calculate the decay constant / ? and tt mass m - jf as functions of the chemical potential 利用我们得到的核物质中的有效作用量，我们计算了介子的衰变常数和质量，他们都是化学势的函数。
There are two frameworks the temperature field theory and the relativistic hadronic model theory for studying nuclear matter at finite temperature and finite density 热密核物质研究的理论基础主要是有限温度场论和相对论性的强子动力学模型理论。
The criminal heavy case 2003 , 2005 and so on the criminals know the crime the disease symptom fascist terror use nuclear matter to carry on the long - term murder completely 罪犯重案件2003 、 2005等罪犯全部知晓罪行的病状法西斯恐怖使用核物质进行长期杀人。
Based on the knowledge of phase transition and chaos , we will devote ourselves to explore the relation between the liquid - gas phase transition and chaos , and the size effect on liquid - gas phase transition 而对于核物质，我们从它的相图中可以知道，在低能区会发生液气相变。
