They found that the shift from a vortex-ring to a continuous-vortex gait depended on sufficient forward velocity to provide airflow over the wing during the upstroke similar to that during the downstroke.

他们发现，转移，从涡环一个连续涡步态依赖于足够的前进速度提供的气流，机翼在upstroke类似，在

In the vortex ring gait, the upstroke is aerodynamically passive (there is no bound circulation during this phase, and hence no trailing vortex), and the wings flex and move close to the body to minimize drag.

在涡环的步态， upstroke是aerodynamically被动的（是没有约束，流通在这一阶段，因此没有尾随涡），和翅膀flex和动议接近身体，以减少阻力。
