Airflow is the way air moves through or around something — a steady stream, not just “there is air.” You meet it with machines and bodies: air flowing through an engine, over a car or a plane, through a building’s vents, or in and out of your lungs.

Airflow is the way air moves through or around somethingairflow是空氣穿過或繞過某個東西移動的方式 — a steady stream是穩定的氣流, not just "there is air."而不只是「有空氣」而已。 You meet it with machines and bodies你會在機器和身體上遇到它: air flowing through an engine空氣流過引擎, over a car or a plane掠過車子或飛機, through a building's vents穿過建築物的通風口, or in and out of your lungs或是進出你的肺.

Designers care about good airflow so a room does not feel stale, a laptop does not get too hot, or a plane moves smoothly. The word is a little technical, but the idea is plain: air on the move, in a path.

Designers care about good airflow設計師很在意良好的airflow so a room does not feel stale好讓房間不會感覺悶, a laptop does not get too hot筆電不會太熱, or a plane moves smoothly或是飛機能順暢飛行. The word is a little technical這個字有點技術性, but the idea is plain但概念很簡單: air on the move, in a path空氣沿著一條路徑在移動.

It is almost always a noun (the airflow), not a verb. People do not often use it for a breeze outside; they save it for air moving in a designed space or around a shaped object.

It is almost always a noun (the airflow)幾乎都是當名詞用（the airflow）, not a verb不是動詞. People do not often use it for a breeze outside大家不常拿它來說戶外的微風; they save it for air moving in a designed space or around a shaped object而是留給在設計過的空間裡、或繞著特定形狀物體移動的空氣.
