conductance
电导
the capacity of a material to conduct electricity, measured as the reciprocal of its electrical resistance
电导（conductance）是电阻的倒数；电导率（conductivity）是材料的固有导电能力的量度。
- 1.
A measure of the ability of a body to conduct electricity; the reciprocal of its resistance.
衡量物体导电能力的量；电阻的倒数。
衡量物体导电能力的量；电阻的倒数。；电导率；传导力；[化] 电导
In use
The conductance of this copper wire is very high, so it carries current easily.
To measure the conductance of the solution, the lab technician used a special meter.
If the resistance increases, the conductance decreases because they are inversely related.
the conductance of sth
conductance 通常与 of 连用，表示某物的电导。
The conductance of pure silver is very high.
纯银的电导率非常高。
measure the conductance of sth
measure 后直接接 conductance 作宾语。
We measured the conductance of the sample.
我们测量了样品的电导。
have a high/low conductance
用 high/low 修饰 conductance 来描述导电能力的高低。
This material has a low conductance.
这种材料具有低电导率。
Common mistakes
This metal conductance electricity well.This metal conducts electricity well.
谓语位置需要动词 conduct（导电），不能使用名词 conductance（电导）。汉语“导电”对应动词短语 conduct electricity，因此把 conductance 改为 conducts，句子才符合英语主谓宾结构。
The conductance of electricity in copper is faster than in iron.The conduction of electricity in copper is faster than in iron.
这里描述的是电在铜中传导的过程，应该用名词 conduction（传导）；conductance（电导）是表示导电能力的物理量，不能用 faster 来修饰。将 conductance 改为 conduction 后搭配才正确。

Learner notes
Memory Tip
conduct（传导）+ance（名词后缀）：导体传导电流的能力，就是电导。
Context & Register
语域：formal 常见场景：physics textbooks、engineering reports、scientific journals conductance 是物理学和电气工程中的专业术语，多用于学术论文、教材和技术报告等正式场合。中文通常译为“电导”，指材料传导电流的能力，日常口语中很少使用。
Pronunciation & Spelling
Inductance /ɪnˈdʌktəns/ and reluctance /rɪˈlʌktəns/ rhyme with conductance: their stressed vowel is /ʌ/ and the rest is /ktəns/. Resistance, acceptance, acquaintance, and importance look similar in spelling (ending in -tance) but have different stressed vowels (/ɪ/, /ɛ/, /eɪ/, /ɔːr/), so they do not rhyme with conductance.
