We make a concise review of this method and use it to calculate the radiative decays of the vector mesons, the baryon magnetic moments, the isospin symmetry breakings in π,ρsystem and πNN coupling constants. All of our results agree well with data.

我们对这一方法作了扼要的评述，应用它计算和分析了矢量介子的辐射衰变宽度，重子磁矩，π和ρ体系的同位旋对称性破缺以及πNN 耦合常数的同位旋对称性破缺等，都得到了与实验符合得很好的结果。

The two cubic potentials induce the static and the second-order harmonic parts of the discrete breathers with certain symmetry.

There are three forms of symmetry in virus capsids: icosahedral , helical and complex forms.

壳粒排列的方式使病毒的结构呈几何对称，病毒衣壳有三种对称形式：二十面体立体对称、螺旋对称、复合对称，螺旋结构呈杆状，而二十面体由对称的亚单位组成近似的球状，非对称的衣壳是较复杂的形式，往往与细菌病毒有关。

Papovaviruses are also icosahedral symmetry viruses, but their capsid structures disobey the quasi-equivalence theory. Papovaviruse capsids are all composed of pentagons. Furthermore, these pentagons can not be connected directly, because there is a certain distance among them.

A virus is a unit of infectious genetic material smaller than any bacteria and embodying properties placing it on the borderline between life and non-life. The vast majority of the virus capsid protein assembled into icosahedral symmetry of the structure. Caspar-Klug Theory has become a fundamental concept for the classification of icosahedral viral capsids based on the principle of quasi-equivalence.

二：病毒是比任何细菌都小的感染性遗传物质，介于生命与非生命之间的一类无细胞结构的生物，绝大多数病毒的衣壳蛋白装配成二十面体对称的结构，&准等价&原理是解决严格遵从二十面体对称性的病毒衣壳几何特征的有效而成熟的方法。

The capsids of nearly all spherical viruses adopt icosahedral symmetry .

球状病毒衣壳采用二十面体对称。
