Because the stream moving along the bottom displaces the lighter fluid upward, a force must be provided to overcome boundary resistance.
因为沿底部运动的异重流与上部较轻的流体置换，必须产生一种力来克服边界阻力。
Although the resistance force increase of series nozzles makes the average energy of jet flow decreased but it lets the instantaneous energy modulated to impel more fluid resonances.
虽然串联喷嘴阻力损失的增加，使射流平均能量有所降低，但射流的瞬时能量得到了调制，激励出更大的流体振荡。
