【摘要】 在日益发展的节水灌溉工程中 ,U型渠道断面得到了广泛的应用 ,但是在确定渠道断面尺寸的水力计算中 ,大都采取对高阶隐函数进行试算或图角法来完成 ,过程十分繁琐 ,为了方便计算 ,本文利用VB6 0进行编程 ,求解U型渠道中的正常水深h0 和流速v,结合实例说明思路 ,结果表明计算精度高 ,便于应用 ,可供水利工作者参考。更多还原

【Abstract】 In the irrigation project of developing saving water, the style of U channel transection has been used widely. To get dimension of the style of channel transection in irrigation calculation, the high level concealment math, which calculates again and again or illustrated by charts and diagrams are applied to finish transection design. During the course of calculation, it is very complexity. In order to convenience to calculate volume of the nature water depth. and velocity of flow, the writer utilizes VB6 0 to programme, at the same time combines example to explain the train of thought. The result shows the calculation precision is high. It can be referred to the hydroelectric works.更多还原
