常见错误

❌ 错误:The catenary is used to describe a straight line.
✓ 正确:The catenary is used to describe a curved line.

catenary 特指曲线形状,而非直线;中文学习者可能误以为它泛指线条,应强调其曲线特性。

❌ 错误:I saw a catenary on the wall.
✓ 正确:I saw a catenary formed by the hanging cable.

catenary 通常指由悬挂物(如链、电缆)形成的曲线,不能单独用于描述静态物体;需明确其形成原因。

近义词辨析

curve

curve 是广义的曲线,而 catenary 特指由重力作用下悬挂的链或缆形成的特定曲线形状,更具专业性。

The road has a gentle curve, but the bridge's cable follows a precise catenary.

arc

arc 通常指圆弧或弧形段,强调几何形状;catenary 则基于物理原理,描述自然悬挂的曲线,常见于工程应用。

The arch of the doorway is semicircular, whereas the suspension bridge uses a catenary for support.
