双语例句

• Analytic method for determination of detachment rate of concentrated flow in erosion rills
  确定侵蚀细沟集中水流剥离速率的解析方法

• Shallow water flow velocity measuring systems for flow velocities in hill-slope rills and/ or watershed water channels;
  薄层水流流速测量系统测量坡面流及其流域内沟道中水流速度；
• Roughness coefficients in rills that are easily affected by the slope gradient, are closely related to Reynolds number.
  细沟流阻力系数的大小与水流雷诺数有关，但其变化趋势受到坡度的影响。
• The results showed that the average quantity of rills and the rill length per unit area in this watershed increased from lower reach to upper reach;
  结果表明，该流域毛沟数量和单位面积毛沟长度从下游到上游呈递增趋势；
• Both runoff erosion and splash erosion in rills is calculated at the same time when its runoff is less then 6 mm.
  当坡面细沟水流平均深度小于6mm时，在细沟内同时进行水流侵蚀和降雨溅蚀的计算。
• Analytic Method for Computing Sediment Concentration in Eroding Rills on Steep Slope
  确定陡坡细沟侵蚀含沙量的解析方法
