简介：这贡献考察Arima和Iachello的交往的波色子模型的对称性质。当动态对称的概念是时现在熟悉的，这未必那么为部分动态对称和伪的扩大观点是动态对称，它能漂亮地在交往的波色子模型的上下文被说明。分析的主要结论是动态对称是少见的当时他们的部分并且伪延期是无所不在的。

简介：象在旋转液体的范围和磁盘一样的身体的相互作用导致新奇流动结构。在环绕的方向的主要打漩流动被一个第二等的运动在南方的飞机附加。流动被在轴的中心通过一个洞介绍墨水设想并且在在交往的身体之间的中央飞机放射状地散布了。流动结构取决于身体，他们的几何安排和旋转速度给的雷纳兹数字的形状。观察流动结构与PIV测量和数字模拟产生了进一步的调查。关键词旋转液体-模式形成-再通行地区-交往的身体-流动可视化CLC数字O351.3
