摘要
均质地层和定流量条件下均衡纵剖面的形成过程与最速滑降问题类似。从最小耗能原理出发,用大量的室内实验成果验证了理想的均衡纵剖面应最接近于一条摆线,从而证实了理论推求的结论,并为均衡纵剖面理论的实践应用打下了坚实的基础。
In condition of uniform stratum and unchanged flow, the process of equilibrium profile forming is similar to a mathematic question-Toboggan slide with the least time. Starting from theory of minimum energy dissipation, It is discussed and verified through indoor experiment that a theoretical equilibrium profile should be a rotation wheel line. This has not only proved that the conclusion coming from theoretical research is right, but given a solid theoretical foundation to further practical use.
