This control method has the advantages of producing minimum level oscillation, and of maximum response speed of the channel water mass to discharge change.
这一控制法产生的水位波动最小，并使渠内水体对流量的变化有最快的反应速度。
On the other hand, climate change is likely to alter river discharge, impacting water availability and hydropower generation.
另一方面，气候变化会改变河道流量，进而影响水资源可用量和水力发电。
And water is used in cold test. Through changing operating conditions, throat area and back pressure, the change rule of discharge coefficient and pressure recovery factor were found.
通过大量冷态试验，在大范围变化工况、变化喉部面积及变化背压条件下，利用水对低温流量控制系统进行研究，得到了流量系数、压力恢复系数的变化规律。
