HEAT TRANSFER

定义 Definition

“heat transfer” 指热量从一个物体、区域或系统传递到另一个的过程,通常由于温度差而发生。常见方式包括传导(conduction)对流(convection)辐射(radiation)。(在工程与物理语境中最常用;在某些学科里也可进一步讨论相变传热等。)

发音 Pronunciation (IPA)

/hit trnsf/

例句 Examples

Heat transfer happens when a hot cup warms your hands.
热传递发生在热杯子把你的手暖热的时候。

Engineers calculate heat transfer to design efficient cooling systems for computers, where conduction, convection, and radiation all play a role.
工程师会计算热传递来设计高效的计算机冷却系统,在其中传导、对流和辐射都起作用。

词源 Etymology

“heat” 源自古英语 htu(热、热度);“transfer” 来自拉丁语 transferre(搬运、转移),由 *trans-*(跨越)+ ferre(携带)构成。合起来,“heat transfer” 字面义就是“把热量转移过去”,后来成为物理与工程学中的标准术语。
