The slipstream is the band of quieter, lower-pressure air just behind something that is moving fast — a car, a motorbike, a bicycle, a plane. The vehicle punches a hole in the air; right behind it, the air does not push back as hard.

The slipstream尾流 is是 something that is moving fast快速移動的東西 — a car, a motorbike, a bicycle, a plane —汽車、摩托車、腳踏車、飛機— just behind正後方 the band of quieter, lower-pressure air那一段比較安靜、氣壓較低的空氣。The vehicle這個載具 punches a hole in the air;會在空氣中撞出一個洞; right behind it,就在它正後方 the air空氣 does not push back as hard反推回來的力道沒那麼大。

Riders and drivers use that on purpose: if you sit in someone’s slipstream, you need less power to keep the same speed. Cyclists call the tactic drafting; in a race you will see a line of riders tucked in each other’s slipstream to save energy, then one of them pulls out to pass. Cars and motorbikes do the same on a track.

Riders and drivers騎士和駕駛 use that on purpose:會故意利用這一點: if you sit in someone's slipstream,如果你待在別人的尾流裡 you need less power你就不需要那麼多動力 to keep the same speed來維持同樣的速度。Cyclists自行車手 call the tactic drafting;把這個戰術叫做「跟騎」; in a race在比賽中 you will see你會看到 a line of riders一整排選手 tucked in each other's slipstream躲在彼此的尾流裡 to save energy,省力 then one of them pulls out to pass然後其中一人再拉出來超車。Cars and motorbikes汽車和摩托車 on a track在賽道上 do the same也是做一樣的事。

And in books, slipstream is also a kind of writing that sits between science fiction and ordinary literary fiction — that use was coined by the cyberpunk writer Bruce Sterling in 1989. The racing sense is the one you will meet in sport and physics talk; the book sense is a specialist label.
