Translation guide
The ability of a material to conduct electricity, heat, or sound. In Japanese, the term depends on what is being conducted.
The ability to conduct electric current.
Standard term for electrical conductivity, used in physics and engineering.
銅は導電率が高い。
Copper has high electrical conductivity.
More explicit term for electrical conductivity, often used in technical contexts.
この材料の電気伝導率を測定する。
Measure the electrical conductivity of this material.
Refers to the property of being electrically conductive, often used in material descriptions.
このポリマーは導電性がある。
This polymer has electrical conductivity.
The ability to conduct heat.
Standard term for thermal conductivity.
金属は熱伝導率が高い。
Metals have high thermal conductivity.
Refers to the property of being thermally conductive.
このセラミックは熱伝導性に優れている。
This ceramic has excellent thermal conductivity.
The general concept of conductivity, often in scientific contexts.
General term for conductivity, used when the type is clear from context.
伝導率の単位はジーメンス毎メートルです。
The unit of conductivity is siemens per meter.
Sometimes used for electrical conductance or conductivity, but less common than 導電率.
The ability to conduct sound waves.
Technical term for acoustic conductivity, rarely used outside specialized fields.
この素材の音響伝導率は低い。
The acoustic conductivity of this material is low.
Descriptive phrase meaning 'property of transmitting sound', used when technical term is unnecessary.
水は音を伝える性質がある。
Water has the property of conducting sound.
Both mean electrical conductivity. 導電率 is more common and shorter. 電気伝導率 is more explicit and used in formal technical writing.
伝導性 (e.g., 導電性, 熱伝導性) refers to the property or quality of being conductive, while 伝導率 refers to the measured value or coefficient. Use 伝導性 when describing a material's characteristic, and 伝導率 when stating a numerical value.
溶液の導電度を測る。
Measure the conductivity of the solution.
