前池

分析表明，水位调节模式下调节系统的稳定条件容易满足，稳定域很大，前池时间常数Tq大的更有利于调节系统稳定。

The results show that the water-level controlling system has wide stable domain and stable condition is easy satisfied and the domain is larger when the forebay time constant Tq is bigger .

由于前池长度足够长，总体来说，前池水流较平顺；PIV技术就是采用粒子跟踪技术来测定流场的速度及其它运动参数的。

Because of the enough length of forebay , in general , the flow in the forebay is smooth . PIV ( Particle Image Velocimetry ) is to use particle tracking to measure flow speed and other motion parameters .
