conductivity
含义: The ability of a material to conduct or transmit heat, electricity, or sound, measured as the reciprocal of resistivity in the case of electrical conductivity.
Conductivity is a fundamental physical property used to characterise materials. Electrical conductivity determines whether a substance is a conductor, semiconductor, or insulator. Thermal conductivity governs heat transfer and is critical in building insulation and electronic cooling. In environmental science, water conductivity serves as an indicator of dissolved mineral content and pollution levels.
