conductance — 名詞

1. how easily electricity or heat can move through a material; in physics, it is ca

1.名詞C2
釋義

電導；熱導

電或熱通過物體的容易程度

how easily electricity or heat can move through a material; in physics, it is calculated as one divided by the material's resistance.

例句

Copper has very high conductance, so engineers use it for most home wiring.

銅的電導非常高，因此工程師用它做大部分家用電線。

subject + has + high/low conductance

Daichi measured the conductance of the salt water with two thin metal probes.

Daichi 用兩根細金屬探針測量鹽水的電導。

measure + the conductance of + [substance]

常見搭配
  • high conductance
  • low conductance
  • thermal conductance
  • electrical conductance
  • measure conductance
  • increase conductance
同義詞
  • conductivity

    very close; in physics, conductivity refers to a material property, while conductance refers to a specific object's value

  • permeability

    broader; covers flow of liquids and gases, not just electricity or heat

反義詞
  • resistance

    the mathematical opposite — conductance equals 1 divided by resistance

  • insulation

    the practical opposite; a material with low conductance acts as insulation

用法筆記

Almost always uncountable. Subject is usually a material (copper, water, wood) or a component (battery, wire). Often modified by 'thermal' for the heat-flow sense and 'electrical' for the electricity sense.

常見錯誤

Copper has many conductances.
Copper has high conductance.
uncountable; use a degree word like 'high' or 'low', not a number.
The wire's conductance is strong.
The wire's conductance is high.
describe the level with 'high' or 'low', not 'strong' or 'weak'.
