房间里暖空气的对流形成了一阵微风。
对流
先理解核心含义，再看它在真实句子里的用法。
对流
the transfer of heat through a fluid (liquid or gas) caused by molecular motion
The convection of warm air in the room creates a gentle breeze.
房间里暖空气的对流形成了一阵微风。
指流体中由分子运动引起的热传递；区别于“传导”（conduction）。
流体中通过环流传递热量。
The transmission of heat in a fluid by the circulation of currents.
流体(液体或气体)中因分子运动而产生的热传递
the transfer of heat through a fluid (liquid or gas) caused by molecular motion
热量和水分的垂直运动,尤指在不稳定气团中由上升气流和下沉气流引起的垂直运动。对流和雷暴这两个术语经常互换使用,尽管雷暴只是对流的一种形式。高耸的积云是对流的可见形式。
The vertical movement of heat and moisture, especially by updrafts and downdrafts in an unstable air mass. The terms convection and thunderstorm are often used interchangeably, although thunderstorms are only one form of convection. Towering cumulus clouds are visible forms of convection.
(气象学)大气中因大规模运动导致的热量或其他属性的垂直移动
(meteorology) the vertical movement of heat or other properties by massive motion within the atmosphere
The warm air near the radiator rises by convection, warming the whole room.
散热器附近的暖空气通过对流上升，温暖整个房间。
In a pan of soup, convection creates the rolling motion that carries heat from the bottom to the surface.
在一锅汤里，对流产生翻滚运动，把热量从底部带到表面。
Under the hot sun, convection causes the air above the beach to rise and form a breeze.
在炎热的阳光下，对流使海滩上方的空气上升并形成微风。
of 后接热量或物质，说明对流的对象。
The convection of warm air in the room creates a gentle breeze.
房间里暖空气的对流形成了一阵微风。
作方式状语，常与 transfer、move 等动词搭配。
Heat is transferred by convection through the liquid.
热量通过液体以对流方式传递。
convection 通常作不可数名词，表示抽象的热传递过程。
Convection occurs naturally in heated fluids.
在受热流体中会自然发生对流。
Not this
Convention is an important way for heat to travel in water.
Use this
Convection is an important way for heat to travel in water.
这里把“convection（对流）”误写成“convention（大会；惯例）”，两词拼写相近但意思完全不同。热能通过流体传递的现象应使用convection。
Not this
A convection plays an important role in the weather.
Use this
Convection plays an important role in the weather.
convection在此指对流传热现象，是不可数名词，前面不加不定冠词a。
Focus on the distinctions below. Other candidates are kept compact until a reliable usage note is available.
自然对流
Warm air rises by natural convection, creating air currents.
暖空气因自然对流而上升，形成气流。
强制对流
A fan speeds up cooling by forced convection.
风扇通过强制对流加速冷却。
对流气流
Convection currents in the ocean affect the climate.
海洋中的对流影响气候。
对流烤箱；热风烤箱
Use a convection oven to bake the chicken evenly.
使用对流烤箱把鸡肉烤得均匀。
热对流
Heat convection in the atmosphere drives weather patterns.
大气中的热对流驱动着天气模式。
Use convection naturally, then get feedback on meaning, tone, grammar, and phrasing.

想象热汤：底部受热上升、顶部冷却下沉，形成环形“对流”。记住con-一起+vection携带，热量被流体“带着走”。
语域：formal 常见场景：physics、engineering convection（对流）多用于物理学和工程学等专业领域，属于正式书面用语；常见于教材、论文或技术说明中，日常口语中较少单独使用。
All six words rhyme with convection: each has stressed /ɛk/ followed by /ʃən/ in the -ection ending. Beware lookalikes that do not rhyme, such as convention /kənˈvɛnʃən/ and conviction /kənˈvɪkʃən/.
