1·Their lengths are similar to the lengths of furrows on comparable soils and slope gradients.
对相似的土壤和坡度，畦田长度和灌水沟的长度雷同。
2·The sediment loss gross amount increased by power function with the increase of slope gradients.
泥沙流失总量与坡度呈幂函数递增关系。
3·Irrigation furrows with slope gradients steeper than 2% are difficult to irrigation without erosion.
坡度大于2%时，灌水沟很难避免冲刷侵蚀。
4·The hydrodynamic characters of runoff in the process of rill erosion were studied by using runoff scouring experiment under the different slope gradients and the different flow discharges.
通过不同坡度、不同流量的组合放水冲刷试验，对坡面细沟侵蚀发生过程中的坡面流水动力学特性进行了研究。
5·The investigations on 21 debris flows on mountain slope in Beibei District, Chongqing makes clearly that gradients are very important to debris flow on mountain slope.
对重庆市北碚区的21个坡面泥石流的实地调查表明，坡度对坡面泥石流发生具有重要的控制性作用。
