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。

简介：一条数字途径被执行预言非线性的水波浪的繁殖和转变。数字波浪斜槽被开发基于非周期性高顺序光谱(HOS)方法。斜槽被使用在非线性的波浪的繁殖上分析波浪险峻和波长的效果。结果证明为低险峻的波浪，波浪侧面和波浪精力光谱是稳定的，并且繁殖能被线性波浪理论预言。为中等险峻的波浪和陡峭的波浪，在一个波浪组与在波浪之间的相互作用联系的效果变得重要并且一列火车开始，正弦曲线波浪可以急速地从它的原来的位置在短距离以内改变它的形式。
