阀门接近全开至全开后，输水廊道第一分流口有空化现象。

But , there exists cavitation phenomenon needed to pay attention to the first crossover culvert when the valve is near and after whole opening .

由于永久船闸运行时，水位落差大，变化频繁，输水廊道水流流速大，对混凝土外观质量要求非常高。

Because of the frequent water level fluctuations and the high velocity of water in the corridor for water , the concrete surface must be with high quality .

本文针对输水廊道的水流特点，应用动量定理建立起输水廊道沿程增量流微分方程，并给出一种数值解法。

In accordance with flow characteristics of the catch-water channel , linear increment flow differential equation has been obtained by momentum law , and a numerical method has been made .

立轴旋涡现象在电站引水管、溢洪道、导流隧洞、大型水泵、船闸输水廊道等进水口前时有发生。

The vertical vortex is a normal hydraulic phenomenon before intakes of hydraulic structure such as diversion pipeline of hydraulic power station , spillway , diversion tunnel , high-power water pump , canal for water conveyance .

麻石船闸在灌水过程中，输水廊道的阀门井处大量进气。空气经廊道进入闸室，在闸室中形成大气泡，威胁过闸船舶安全。

In the course of filling of Mashi Lock , a lot of air from the valve well comes into the culvert so as to produce many big air bubbles in the chamber , which is dangerous to the passing ships .
