The effect of temperature on thermal conductivity is different for metals and nonmetals. In metals, heat conductivity is primarily due to free electrons. Following the Wiedemann–Franz law, thermal conductivity of metals is approximately proportional to the absolute temperature (in kelvins) times electrical conductivity. In pure metals the electrical conductivity decreases wit…
熱伝導率(ねつでんどうりつ、英語: thermal conductivity)とは、温度の勾配により生じる伝熱のうち、熱伝導による熱の移動のしやすさを規定する物理量である。熱伝導度や熱伝導係数とも呼ばれる。記号は λ, κ, k などで表される。 国際単位系(SI)における単位はワット毎メートル毎ケルビン(W/m … Meer weergeven 熱伝導率は温度勾配に対する熱流密度の比として定義される 。 すなわち、熱流密度を j、熱力学温度を T として、勾配 grad により と表したと … Meer weergeven • レーザーフラッシュ法(英語版) • 定常熱流法・平板熱流計法 • 熱線法 Meer weergeven 熱伝導率の逆数を熱抵抗率という。また、熱伝導率に似ているが異なる物理量として • 熱拡散率 - 温度勾配により運ばれる温度(熱エネルギー)の拡散係数 • 熱拡散係数 - 混合物に温度勾配がある場合に、熱拡散により濃度勾配が生じる時の大きさを規定する物理量 Meer weergeven • 『熱伝導率』 - コトバンク Meer weergeven the dark knight internet archiveWebApproximate models for the lattice thermal conductivity of alloy thermoelectrics J.
