传导性；传导率
先理解核心含义，再看它在真实句子里的用法。
传导性；传导率
the transmission of heat or electricity or sound
The conductivity of copper is very high.
铜的电导率非常高。
泛指传导热、电或声音的性质；导电率专指导电能力。
材料传导电、热、流体或声音的能力
The ability of a material to conduct electricity, heat, fluid or sound
电阻率的倒数
The reciprocal of resistivity
Copper is often used in wiring because of its high electrical conductivity.
铜常用于布线，因为它的导电率很高。
The conductivity of this material changes with temperature.
这种材料的传导性随温度变化。
Researchers measured the sound conductivity of the new insulation.
研究人员测量了这种新型隔音材料的传声性。
The conductivity of copper is very high.
铜的电导率非常高。
conductivity 通常作不可数名词，但复数形式 conductivities 表示不同类型的传导率或测量值。
This material has low thermal conductivity.
这种材料的热导率很低。
We measured the conductivity of the solution.
我们测量了这种溶液的电导率。
Not this
This material has a good conductivity.
Use this
This material has good conductivity.
conductivity 在表示性质时是不可数名词，前面不加不定冠词 a；若要说“导电性好”，直接用 good conductivity。只有给出具体数值时才会用 a conductivity of ...。
Not this
Copper is known for its high conductive.
Use this
Copper is known for its high conductivity.
conductive 是形容词，不能放在物主代词 its 后面充当名词宾语；表达“高导电性/高电导率”需要用名词 conductivity。改正后句子结构才正确。

联想 conduct（传导）→ 电流顺畅传导的本领，就是 conductivity（电导率）。
语域：formal 常见场景：物理学文献、化学/材料科学报告、电子工程手册 conductivity 是比较正式的科技用语，多用于学术写作、实验报告或工程文献中，指材料传导热、电或声音的能力；日常口语中较少出现。
复数形式为 conductivities，注意拼写是 -ies 而不是 -ys。
