In the sewer pipe with high energyslope, there always occurs the high velocity flow, and its hydraulic calculation is beyond the range of wastewater design specification.
大比降排水管水流通常为高速水流，其水力设计已经超过排水设计规范范畴。

The basic theory of soil and water loss research has been provided by combining the several physical laws of energy with rain and runoff on slope.
把能量中的几个物理定律同降雨、坡面径流联系起来，为进一步研究水上流失提供了理论基础。

This article obtains from the runoff energy, in the room in the artificial rain experiment foundation, analyzed the slope tillage measure to the runoff energy reduction function.
