“热对流”的英语表达是 "thermal convection" 或更简洁的 "convection"(在上下文明确是热学相关时)。
Thermal convection:更强调与热相关的对流现象,常用于科学或工程领域的正式表述。
Convection:在多数日常或专业讨论中,若上下文明确涉及热传递,可直接用此词。
例句:Heat transfer through thermal convection occurs when a fluid (like air or water) moves and carries heat with it. (热对流发生在流体如空气或水移动并携带热量时。)
Convection is one of the three main methods of heat transfer, alongside conduction and radiation. (对流是与传导和辐射并列的三种主要热传递方式之一。)
