附加流速法通过向节流管线内注入轻质的附加流体降低了节流管线的压降，可以很好的解决上述的压井难题。

Additional flow rate (AFR) method can overcome this problem beautifully by inject a kind of light and thin fluid into choke line to drop its pressure loss.

较总流量分析法，仅能给出明渠断面平均流速有所改进。

There is improvement as compared with the method of total flow which only gives the average velocity of transverse profile of open channel.

目前，我国明渠测流仍采用传统的特设量水设备法、水尺法、流速仪法等。

At present, we are still using the traditional way: AD hoc volume of water equipment, water gauge, velocity meter etc.
