1.名詞C1
釋義

流線

流體中粒子平滑運動的路徑線

an imaginary line that shows the path a single particle of a liquid or gas follows when it flows smoothly around a solid object, without forming swirls or eddies

例句

The engineering students drew streamlines around the wing cross-section to study lift.

工程系的學生在機翼截面周圍畫出流線，用來研究上升力。

common collocations: draw streamlines, streamlines around [object]

When the airflow is steady, the streamlines remain parallel and evenly spaced on the computer model.

當氣流穩定時，電腦模型上的流線保持平行且間距均勻。

streamlines remain parallel (describes smooth flow)

同義詞
  • flow line

    less common; used interchangeably in some engineering contexts

  • path line

    distinguished in technical fluid dynamics — a path line traces an actual particle, while a streamline is a snapshot

文法句型

streamlines of [fluid] around [object]

用法筆記

Countable; technical term most common in fluid dynamics textbooks and engineering contexts. Often used in the plural ('streamlines') to refer to the full pattern of flow.

常見錯誤

❌The streamline of water goes around the rock.
✅The streamlines of water around the rock show how it flows.
💡'streamline' as a noun usually refers to the theoretical path line, not to the visible flow itself.

釋義

流線形

為減少流體阻力而設計的平滑外型

a smooth outer shape given to a car, aircraft, train, or other moving object so that air or water can pass over it with very little resistance

例句

同義詞
  • aerodynamic design

    broader term covering all aspects of reducing drag, not just the shape

  • smoothing

    less precise; describes the physical action without the technical goal of drag reduction

文法句型

streamlining of [object]

have streamlining

用法筆記

Uncountable when referring to the concept or design feature; countable when referring to a specific instance of streamlining on a particular object.

室內設計師從汽車界借用了流線造型，創造出表面平滑流暢的家具。

同義詞
  • sleekness

    focuses more on the polished, glossy finish than on the contour itself

  • smooth contours

    more literal description of the lines and curves

反義詞
  • angularity

    design characterised by sharp edges and corners rather than flowing curves

文法句型

streamlining in [product/design]

用法筆記

This sense is about aesthetic style inspired by aerodynamic shapes, not about functional drag reduction. Common in design history and product styling discussions.

常見錯誤

❌The streamlining of the office chair helps it move faster.
✅The streamlining of the office chair gives it a modern, sleek look.
💡This sense is about appearance, not actual speed.
