這就是蒼蠅如何顛倒著降落

Flies alway seem to land perfectly on almost any surface, at almost any angle, but researchers at Pennsylvania State University have found that their upside-down landings are much more complicated.

蒼蠅似乎總是完美地降落在幾乎任何表面，幾乎任何角度，但賓夕法尼亞州立大學(xué)的研究人員發(fā)現(xiàn)，它們的顛倒著陸要復(fù)雜得多。

A new study revealed how flies use various barrel roll and flipping maneuvers to land on upside-down surfaces.

一項(xiàng)新的研究揭示了蒼蠅如何使用各種滾桶和翻轉(zhuǎn)的動作來降落在顛倒的表面。

Various videos from the study demonstrate how flies can adjust course in mid-air to make a perfect landing.

這項(xiàng)研究的各種視頻展示了蒼蠅如何在半空中調(diào)整航向，以實(shí)現(xiàn)完美著陸。

The researchers even included a few clips of failed landings by the flies. (I guess even flies aren't perfect in this regard.)

研究人員甚至還收錄了幾段蒼蠅降落失敗的視頻。(我想即使是蒼蠅在這方面也不是完美的。)

The feat of landing perfectly upside-down seems daunting, but flies rely on visual queues to make adjustments. They must decide on the best way to flip in 50 milliseconds or less.

完全倒著著陸的壯舉似乎令人生畏，但飛機(jī)依靠視覺隊(duì)列進(jìn)行調(diào)整。他們必須決定在50毫秒或更少的時(shí)間內(nèi)翻轉(zhuǎn)的最佳方式。

The scientists behind the study hope that by analyzing flies' lightning-quick movements, engineers might be able to emulate their landing patterns in future iterations of drones and flying robots.

這項(xiàng)研究背后的科學(xué)家希望，通過分析蒼蠅閃電般的快速運(yùn)動，工程師們或許能夠在未來的無人機(jī)和飛行機(jī)器人的迭代中模仿它們的著陸模式。
