平坡 meaning in English
horizontal slope
near level grade
near-level grade
zero slope
Examples
- With the in - built drip irrigation belt and thin wall chip irrigation belt taken as examples , the flow rate distribution and hydraulic losses of drippers along capillary tubes at different inlet pressures were measured under the conditions of horizontal slope and slope gradients of 0 . 5 % and 1 % , then the uniformity of capillary tubes was calculated at different slope gradients and pressures in consideration of the manufacture deviation of drippers
摘要以内镶式滴灌带和薄壁滴灌带为研究对象，测定了平坡、 0 . 5 %坡度和1 %坡度时，不同入口压力下滴头沿毛管的流量分布和水力损失，并结合滴头的制造偏差，计算得出不同坡度和压力条件下滴灌毛管的均匀度。 - Based on the principles of runoff agriculture and sloping fields runoff moisture balance of natural precipitation , the dynamical regularity of soil moisture in rainfall and fertilizer harvest terrace was studied , which can provide a scientific basis for improving the utilization of natural precipitation
摘要应用径流农业和坡地降雨径流水量平衡原理，对代表燕辽低山丘陵区典型区域不同平坡比的集流聚肥梯田土壤水分动态变化规律进行了研究，为提高该区自然降水利用率提供了科学依据。
