See how strong and steady my wingbeat has become!

看我的膀拍打得多么有力稳健！

With a wingbeat frequency of about 600 beats per second...the insects are able to lift themselves lightly off their host.

凭借每秒约600次的频率，雌蚊子能轻巧地飞离宿主。

They're actually talking to each other with their wingbeat frequencies.

他们实际上是用频率互相交谈。

Another burst of lifting wingbeats and they came out over rocks, silver-frosted angles and outcroppings in the starlight.

又一拍打，它们飞过岩石、银霜角和星光下的头。

A bee the size of a helicopter lands near you, making the ground shake, as its hairy carapace vibrates with each wingbeat.

一只和直升机般大的蜜蜂近着陆，它毛茸茸的甲壳随着翼拍动，进而使地面震动。

And from there, an energy-efficient form of echolocation developed, with bats exhaling - and squeaking - in time with their wingbeats.

从那里开始， 一种节能的回声定位形式得到发展，蝙蝠随着拍打膀而呼气 - 并发出吱吱声。

The males even manage to imitate the sounds of small birds—the wingbeats of small birds as they fly over or at the predator.

雄性甚至设法模仿小鸟的声音——小鸟飞过或扑向捕食者时拍打膀的声音。

Hummingbirds however, turn their wrists during the upstroke, changing their wing's angle to flap in a figure 8 pattern that continually generates lift throughout their wingbeats.

然而，蜂鸟上击时转动手腕，改变膀的角度，以 8 字形模式拍打，整个拍过程中不断产生升力。

The bot only weighs 175 milligrams, about the same as a raindrop, so to keep it from losing control, they added underwater stabilizers, and slowed down the wingbeats.

该机器人仅重 175 毫克，与雨滴差不多，因此为防止其失控，他们添加了水下稳定器，并减慢了拍速度。
