conduction(傳導)是物理學和工程學中的一個核心概念,指熱量或電荷通過介質(物質)内部進行傳遞的過程,而不伴隨介質本身的宏觀運動。其本質是能量(熱能或電能)通過介質内部粒子(如分子、原子、電子)的相互作用或定向移動,從高溫區域傳遞到低溫區域,或從高電勢區域傳遞到低電勢區域。
具體可分為兩大類:
熱傳導 (Thermal Conduction):
電傳導 (Electrical Conduction):
核心要點
理解傳導原理對于電子設備散熱設計(如CPU散熱器)、材料科學(開發導熱/導電或絕緣材料)、電力傳輸、建築保溫等諸多工程和技術領域至關重要。
“Conduction” 是一個物理學術語,主要指熱量或電能通過物質直接傳遞的過程,常見于以下兩種形式:
如需更專業的科學公式,例如熱傳導方程(傅裡葉定律): $$ q = -k abla T $$ 其中 ( q ) 為熱流密度,( k ) 為熱導率,( abla T ) 為溫度梯度。
