Flying fish rely on a similar flow of accelerated air from their pectoral fins to provide lift to their smaller pelvic fins.
同样，飞鱼借助胸鳍所产生的加速气流，就可以对较小的腹鳍产生一定的提升作用。

Then they popped the fish into a wind tunnel to calculate their lift-to-drag ratios, sometimes called the glide ratio.
之后，将其放入风洞以计算升阻比，有时也被称为滑翔比。

The water flow velocity in the suction pipe, which is crucial for evaluating the performance on pumping fish, can be measured by the pumped water flow rate of the riser in an air lift pump system.
