• thermal 本词

  Describes things that relate to heat itself, such as heat-sensitive equipment or warmth-trapping clothing, rather than an object's own temperature being high.

  描述与热本身有关的东西，比如对热敏感的设备或保暖的衣物，而不是说某个物体本身的温度很高。

  The company sells thermal paper for old fax machines and cash registers.

  这家公司为老式传真机和收银机出售热敏纸。

• fiery

  Emphasizes intense, blazing heat, almost like fire itself; stronger and more vivid than hot, and rarely used for ordinary warm food or drinks.

• heated

  Means warmed up by an outside process or device, such as a seat or pool, implying the heat was added rather than natural or inherent.

  指通过外部设备或过程被加热，比如座椅或泳池，暗示这种热是后来添加上去的，而不是天然或本身固有的。

Hot, thermal, fiery, and heated relate to heat. Hot is the everyday word for high temperature. Thermal relates to heat itself, like heat-sensing gear. Fiery means intense, blazing heat. Heated means warmed by an outside process. Their temper and argument senses are not compared here.

这四个词都与「热」有关，但用法不同：hot 是最基础、最常用的说法，可以自由修饰食物、天气或物体；fiery 强调像火一样猛烈灼热，语气比 hot 更强；heated 强调经过外部加热才变热，而不是本身固有的高温；thermal 强调「与热有关、用来保温」，很少直接说某物本身「是 thermal 的」来表示烫。这里不比较 fiery 的「脾气火爆的」义和 heated 的「（争论、情绪）激烈的」义。
