最小能耗率原理及在河流动力学中的运用

摘要

缓慢黏性流体的最小能耗率原理在1868年提出后受到了人们的高度关注。最小能耗率原理在不断发展和完善的同时，在河流动力学领域的应用中出现的问题也越来越多，受到水利界的高度重视。分析了最小能耗率的原理和其在河流动力学中的运用，希望能为此研究工作提供参考。%The minimum rate of energy principle of viscous fluid slowly after 1868 made by the people’s attention. The minimum rate of energy dissipation at the same time, continuous development and improvement of river dynamics occurring in the field of application problems more and more highly valued water conservancy sector. The principle of minimum rate of energy and its use in the river dynamics, hoping to provide a reference do this research.
