简介：真实波浪是multidirectional波浪。在现在的学习，为为产生multidirectional的开车信号挥动的波浪制造者的计算方法在物理波浪盆组织被建议。它的有效性被事件边界条件被建议方法的使用为决定的一个数字模型首先证实。然后，multidirectional波浪组的物理模拟在实验室波浪盆被执行。multidirectional飘动与的试验性的结果表演期望波浪groupiness，它包括不仅它的组高度而且它的组长度，能令人满意地在物理波浪盆在指定位置被产生。

简介：在在煤和煤的器官的功能的组的踪迹元素之间的关系，另外一些芳香的结构，被使用曲线适合红外线的系列调查。簇分析也根据与踪迹元素的器官的组的亲密关系的度被执行。结果证明有可能性，踪迹元素，特别LREE，被绑在中间的等级煤的外部器官的功能的组大分子。绑踪迹元素的最可能的功能的组是氢氧根，并且到更少度，不对称的-CH3并且>拉长的CH2，拉长的-CH3，等等。到不同的功能的组的踪迹元素的亲密关系的度变化。趋势遵守踪迹elements—the的自然结构的变化法律周期的法律。从这个常规趋势的一些踪迹元素的偏差被归因于内在的“confusiondegree”的偏差(常规臼齿的熵)煤盆，它被内部、外部的因素在进化期间影响的事系统。
