At the same time, due to 2~1S_0、 3_1S_0 are the radical excitations of 1~1S_0,we can use Regge trajectory on the (n,M~2)-plane with the approximate same slope to describe the mass of isoscalar of 3~1S_0 nonet (1926MeV). The two results derive from different ways are approximate. 2 The mass of the isodoublet of 2~3S_1 nonet is analyzed in the quarkonium-quarkonium mixing scheme, the results (1584±16.7MeV) is far from the K~*(1410)(1414±15MeV). 3 Based on "glueball dominance" picture, we establish glueball-meson mass relations. For the 2~ glueball mass and 4~ glueball mass used as input parameters, these relations predict the mass of isoscalar of 1~3F_4(4~)(2076±19.66MeV).

的质量(1900±12MeV)；同时考虑到2~1S_0、3~1S_0为1~1S_0的径向激发态，在(n，M~2)雷吉轨迹图中应该具有近似相同的斜率，利用雷吉轨迹可以得到其对应质量为(1926MeV)，两种方法得到了两个十分自洽的结果。2在介子—介子混合框架下，对2~3S_1介子九重态中同位旋二重态的质量给出估计，得到(1584±16.7MeV)，这个结果相对于K~*(1410)=1414±15MeV有较大的偏离。3在胶球为主的图像下，利用介子—胶球质量关系，选择2~与4~胶球的质量作为输入参数，我们得到1~3F_44~(介子九重态中同位旋标量态？

In the quarkonium-quarkoniumglueball mixing scheme, we quantitatively present the quarkonia-glueball content of the isoscalar scalar states and the isoscalar pseudoscalar states, and find that it is necessary to introduce additional glueball components in the ground isoscalar pseudoscalar mesons.

在介子—介子—胶球混合的框架下，我们定量地给出了同位旋为零的标量态和同位旋为零的赝标态的夸克-胶球内容，发现基态同位旋为零的赝标介子中有必要引入附加的赝标胶球成分，标量介子和标量胶球间存在强烈的混合。

As for the study of isospin in intermediate energy HICs, we've investigated how bothstength and density dependence of symmetry potential affect many measurableobservables, such as the yield, phase-space, and isospin distributions of fragments, as wellas the correlations between Intermediate-Mass-Fragment multiplicity 〓 andCharged-Particle multiplicity 〓 Light-Charged-Particle multiplicity 〓 andNeutron multiplicity 〓.

近年来，对QCD的研究已经扩展到有限同位旋密度的范围，而研究QCD在有限同位旋密度下的性质对调查致密星体、同位旋反对称核物质以及中能的重离子碰撞都有重要的意义。

In addition, the momentum dependence of the nuclear mean field potential has been shown for the first time to be important for isospin diffusion in HIC''s and a explicit expression for the density dependence of the symmetry energy has been obtained by fitting the experimental data.

同时在国际上首次研究了核平均场的动量相关性对重离子碰撞中同位旋弥散的影响，发现核平均场的动量相关性对同位旋弥散有重要的影响。

Since the production of RNB provides a new isospin freedom for nuclear physicsresearch, study on the isospin effect becomes a very interesting topic.

放射性束流的出现为核物理提供了一个新的同位旋维度，因此对同位旋效应的研究引起了人们极大的兴趣。
