简介：这篇论文在为一把新奇错流扇子与一个噪音实验获得的远地里借助于数字方法和健全压力调查在来源的波动的压力和速度之间的关系。在一把错流扇子的波动的压力和速度的频率特征被分析借助于光谱分析和小浪变换。大旋涡模拟在套墙上获得的波动的压力与实验的相比并且显示出好同意。从光谱健全来源的分析，波动的压力达到顶点，这被发现在远地里与健全压力相应。

简介：在这份报纸，在关上的geodesics的存在和完全的noncompactRiemannianmanifolds的体积生长之间的关系被学习。首先，作者证明这的diffeomorphic结果一与nonnegativen歧管部分弯曲，它改进Marenich-Toponogovs定理。作为应用，一条刚硬定理被获得因为nonnegatively弯了开歧管它包含一关门测地学。下次，作者证明关于为有部分弯曲的Riemannianmanifolds的关上的geodesics的不存在的一条定理从在下面跳了由一个否定常数。
