| 摘 要： | 从流体力学角度出发,探讨运动沙粒的集体行为,通过分析Stokes波的近似解,用于刻画风成地貌形态的几何特征.给出各级近似Stokes波剖面图形,与自然界实际风成地貌形态相似,其结果也与风成沙纹的实验观测相一致.

| Abstract: | The collective behavior of sand granule motion was investigated on the basis of fluid dynamics,and the geometric feature of the patterns of wind-borne landform was characterized by means of analysis of the approximate solution to stokes wave equation.The sectional figures of stokes waves with several order of approximation were given in this paper,being similar to the patterns of wind-borne landform actual in natural world.Its result was also consistent with the actually observed wind-borne sand ripple. |
