摘要
关于矩形收缩断面水深，试算法精度虽可以得到控制，但计算费时，图解法由于制图及查图的误差，精度又欠佳。为此，笔者通过大量的分析验证，提出了一种精度高，计算简捷方便的直接求解法。
As regards the calculation of water depth of converging rectangular sectionalithough the trial methed can control the precision,the trial process is complicated. Becauseof the error in drawing and consulting graph,the graphic method can not guaranee the preci- sion. Through a large amount of analysis, the authors out a simple and high precision for- mula.
