超流动性是某些物质在极低温下表现出的无摩擦流动特性,常见于液氦等量子流体中。

用法要点

句型搭配

通常用作不可数名词,描述物质状态或现象,常见于“exhibit/show superfluidity”或“study/research superfluidity”等结构中。

• exhibit superfluidity
• study superfluidity
• observe superfluidity

介词用法

常与介词“in”连用表示在某种物质或条件下,如“superfluidity in liquid helium”;也可用“of”表示所属关系,如“the superfluidity of helium-4”。

• superfluidity in liquid helium
• superfluidity of helium-4
• superfluidity at low temperatures

语域说明

主要用于物理学、化学等学术领域,属于专业术语,日常对话中较少使用,但在科普或教育场景可能出现。

• academic paper on superfluidity
• physics lecture about superfluidity
• scientific discussion of superfluidity

常见错误

❌ 错误:Superfluidity is a common phenomenon in daily life.
✓ 正确:Superfluidity is a rare phenomenon that occurs only at extremely low temperatures.

错误:超流动性并非日常生活常见现象,它需要极低温条件。正确用法应强调其特殊性和条件限制。

❌ 错误:Water can show superfluidity.
✓ 正确:Liquid helium can show superfluidity.

错误:水在常规条件下不会表现出超流动性。正确用法应使用液氦等特定物质作为例子,避免误导。

近义词辨析

superconductivity

超导性指电流无阻力流动,通常涉及电子;超流动性指流体无摩擦流动,涉及原子或分子。两者都是量子现象,但应用领域不同。

Superconductivity is observed in metals at low temperatures, while superfluidity occurs in liquids like helium.

viscosity

粘度是流体流动阻力的度量,值越高流动越困难;超流动性则指粘度为零的无摩擦状态,是粘度的极端特例。

High viscosity slows fluid flow, but superfluidity means the fluid has effectively zero viscosity.
