In this paper,the variations in the horizontal and vertical velocities over 6 different transverse dune models are investigated in a wind tunnel by applying the particle image velocimetry(PIV).
通过风洞实验的方法,针对不同形态的6组横向沙丘模型,采用粒子图像测速系统,测量了模型沙丘周围气流水平速度和垂直速度的变化规律。
Morphologic parameters of the simple transverse dunes in Taklimakan Desert show that the morphologic parameters are closely related with the sand supplies.
通过对塔克拉玛干沙漠不同区域发育的简单横向沙丘的形态学示量特征分析 ,表明简单横向沙丘的形态特征与沙源的供应有十分密切的关系 ,沙源的不同丰度导致简单横向沙丘的形态学参数之间有明显的不同 。
The 81 samples were collected over three profiles on typical coastal transverse foredune,which is directly across the foredune,at Changle coastal region in Fujian Province that is one of the most typical coastal aeolian distribution regions in China.
在我国横向海岸沙丘分布的典型地区之一——福建长乐海岸,选择典型的横向前丘,按与横向前丘走向相垂直方向,分三个采样断面近等间距地采集了共81个沙丘表面沉积物的粒度样品,通过对采集样品平均粒径、分选系数、偏度和峰态等粒度参数的计算与分析,研究横向前丘表面的粒度分异特征。
