简介:指纹和在亚洲大陆人沙暴(交流)期间从中央内部蒙古发源的好、粗糙的沙的来源侧面能被用来识别亚洲沙的起源并且当他们旅行,跟踪他们顺风。在中央内部蒙古在各种各样的土地表面收集的土壤样品在一个包围房间用干燥粉末atomizer被重新推迟。重新推迟的沙然后被位于包围房间的底部的二个两分的刺绣花样为罚款(PM_(2.5))取样并且粗糙(PM_(2.5-10))沙分别地。包括水溶性的离子的种类,金属性的内容,和碳的内容,沙的Thechemical作文进一步被分析。从暂停测试的结果显示thes油比罚款包含了更加更粗糙的粒子。而且,在与对方一起的coarses和有的强壮的关联的Mg,K,艾尔,和Fe。Mg的比率,K,Fe(或艾尔)到艾尔(或Fe)并且OC/ECin粗糙的沙能被用作从中央InnerMongolia发源的亚洲沙的指纹。
简介:L2功能的一双Bessel序列产生的双性人内部的产品functionals被介绍。这些functionals是L2和l2的内部产品的经常的multiples,这被显示出,如果并且仅当他们在空间两个都是移动不变的(或时间)并且在里面阶段。这结果然后被使用描绘双框架和L2的双性人直角的Riesz底。

简介:基于液体动力学,热转移和声学的结果,一个计算液体动力学(CFD)方法被利用在一根Rijke管子内学习声学的特征和自我刺激的跳动机制。为了避免解决有限振幅的站的荒谬的边界条件,在Rijkethermo声学的系统飘动,在流动领域里当模特儿的模拟,它联合了有它的外层空间的管子内部,被执行代替传统的方法处于良好的竟技状态内部流动地数字调查。为在包括在热来源,摆动压力和摆动速度附近的空气的不稳定的热上的关系的精力方程的热来源的一个假设被介绍。为了反映Rijke的本质,尖叫,自我刺激的摆动上的模拟借助于它压力,速度和温度的自己的跳动被进行。这个方法能使集中过程稳定并且有效地避免分叉。自我刺激的Rijke管子的物理现象被分析。而且,Rijke管子的自我刺激的摆动上的机制是这个方法上的explained.Based,关于有不同尺寸和嘴的不同形状的Rijke管子的声学的特征的比较研究被执行。模拟结果令人满意地同意了试验性的数据。结果证明这数字模拟能被用来为Rijke管子的设计申请学习嘴的健全压力。
