摘要
明渠水面线推求的关健在于求解能量方程 ,以往求解时常用逐段扫描法、二分法 ,本文通过建立牛顿迭公式 ,并分析其收敛性 。
Solving energy equation which used to scanning method of particial section and two-distribution method is critical for the water surface profile of open cannel. This paper establishes Newton iteration method and analyzes its convergence characteristic. This method supplies idea for solving energy equation about Newton iteration.
