简介:在吝啬地的三地点的BoseHubbard模型以内,偶极的bosonic气体与的通道动力学一周期性地,散布的s波浪的调整被调查。系统经历通道(CDT)的协调破坏转移在下邻居偶极子偶极子相互作用,所在地的相互作用和散布的调制s波浪之中源于相关效果的复杂、富有的协调通道(CT)。特别地,为产生CT(CDT)散布的调制s波浪的区域是最宽(最狭窄)什么时候所在地的相互作用和下邻居偶极子偶极子相互作用一些相关与通道精力和系统的相互作用精力有关仔细珍视,它是。为出现CDT的相关的值能理论上从通道精力和系统的相互作用精力被获得。

简介:我们在一棵锯季度的白杨上使用了声学的测试在声学的波浪上学习木头anisotropy和洞缺点的效果的木材速度和旅行路径,和我们在木头调查了声学的波浪繁殖行为。木材标本首先处于未修改的状况被测试然后在在实验室的声学的波浪的播送时间调节的改变尺寸确定的洞缺点的介绍以后测试了。标本的光线的节上的二维的声学的波浪轮廓地图然后基于试验性的数据被模仿并且分析。当波浪通过木头在各种各样的方向过去了,我们测试了在木头谷物和声学的波浪速度之间的关系。伍德anisotropy在速度和通过超过的木材传递纵的波浪的声学的波浪,和速度的旅行路径上有重要效果光线的速度。而且,洞缺点在木材的光线的节上改变了声学的波浪时间轮廓。从刺激的声学的波浪运输比在未经触动的木头更慢慢地在有缺点的木头在一个洞后面指向这个区域。
