查询词典 spontaneous breaking

The spontaneous symmetry breaking of a mechanical system and its energy degeneracy is discussed.

详细研究了一个力学系统的对称性自发破缺，以及由此引起的能量简并。

We also find that the metal-to-semiconductor transition can be driven by squashing the armchair nanotube along any direction. In case one starts with squashing the tube along a direction that preserves the mirror symmetry, all that needs to be done is to squash the tube to a larger extent, to a point where spontaneous symmetry breaking occurs.

我们并且发现沿任何方向压缩 armchair 碳纳米管都能够使其发生金属-半导体转变，即使我们在开始压缩碳纳米管时保持了其镜像对称性，我们所需要做的只是更大程度的压缩碳纳米管，直到出现镜像对称性的自发破缺。

We have also studied the hydrodynamics of the nuclear matter with spontaneous chiral symmetry breaking based on the Poisson bracket method. The effects of mass are included and the full hydrodynamic equation of pion is given. The possibility of the phase transition to pion condensation is also discussed.

在研究具有手征对称性自发破缺的核物质系统的流体动力学时，我们运用Poisson括号方法，建立了pion介子的完整的流体动力学方程，给出了色散关系并讨论了相变和pion凝聚的可能性。

Under the framework of constituent quark model, according to the effective degrees of freedom used, we have the Glashow-Isgur model , the spontaneous chiral symmetry breaking model, the hybrid model and so on.All of these models are successful to describe the properties of the mesons and baryons.

组分夸克模型是一种非相对论模型，根据所采用的有效自由度的不同，组分夸克模型又可以分为好几种具体的模型，主要有：Glashow-Isgur模型、手征对称自发破缺模型和&杂化&模型等。

Based on granular hydrodynamics,Eggers deduced a simplified flux model which has been successfully used in describing the spontaneous symmetry breaking of granular gas in the compartmentalized system,but so far has not been able to predict the oscillation phenomenon of bidisperse granular gas.

Eggers以颗粒气体动力学为基础得出了简化的理论模型。该模型可以很好地得到分仓中颗粒的布居分聚现象，然而似乎无法用于预测两种颗粒在分仓体系中的布居振荡现象。

The SU (3) chiral symmetry spontaneous breaking should be considered as the strange hadronic matter is studied.
