摘要：
If is shown that the non-Abelian properties of QGP can be got by studying the kinetic equations for QGP beyond the linear response theory. The non-Abelian interaction of the eigenmodes in QGP is found and two quantities describing the non-Abelian properties of QGP are given.

摘要：
In order to simplify the complicated sdg interacting boson model (IBM) Hamiltonian, a microscopic approach based on the Dyson boson mapping and the MJS substitution was presented, and the leading terms in the interaction Hamiltonian were discussed by using numerical investigation. Comparisons of both the calculated levels and the overlap of wave functions between the exact results and the approximations were made to find out negligible part in the Hamiltonian. The results show that the leading terms determined in this paper may provide a way to simplify the complicated calculations and save the computing time.

摘要：
The Levy stable analysis for tandem cascade model is performed. The Levy stable index mu of alpha-model is obtained by both Monte-Carlo simulation and analytical calculation. It is found that mu is increasing when the fluctuation becomes weaker, and vice versa, just as expected. It is shown that the Levy stable index of alpha-model depends mainly upon the model parameter alpha. Its weak dependence on the number lambda of branches in each elementary splitting is due to the normalization of probability in each step. The possible reason of the Levy stable index greater than 2 found experimentally is briefly discussed.

摘要：
The combined effect of several noises has been proposed recently. It has displayed that the presence of the correlation between noises can change the properties of the stochastic processes. In this paper, a general effective Fokker–Planck equation (FPE) with correlated noises is derived. The stationary distributions and the moments of two kinetic models under two correlated noise sources are obtained. The effects of the interference of additive and multiplicative noises are analyzed.

摘要：
By developing the ''tadpole graph method'' including the resummation of the hard thermal loops in the tadpole diagrams, a self-consistent method is proposed in the calculation of effective potential. It is shown that the calculated effective potential at finite temperature in the Higgs model is more self-consistent than the naive calculation. The two difficulties encountered in the naive calculations of the effective potential disappear naturally, The calculated results indicate that the symmetry restoration transition is of the first order.

摘要：
A microscopic approach in appropriately truncated shell model was applied to the description of high spin states for <sup>162</sup>Hf and <sup>164</sup>Hf isotopes. For the description of high spin states, the model contained no additional free parameter. From the point of view of self-consistency, this is a remarkable advantage differing from the phenomenological work. The backbends of the moment of inertia were reproduced well by the calculation. The results show that the approach is able to investigate the yrast states of nuclei in rare earth region.

摘要：
The parameters of the sdg interacting boson model Hamiltonian are calculated for the <sup>104-110</sup>Pd isotopes. The calculations utilize the microscopic procedure based on the Dyson boson mapping proposed by Yang-Liu-Qi and extended to include the g boson effects. The calculated parameters reproduce those values from the phenomenological fits. The resulting spectra are compared with the experimental spectra.
