常温

• 拼音: cháng wēn
• 汉字拆解: 常 = 尚 (phonetic) + 巾; 温 = 氵(water radical) + 昷 (warm, phonetic)

含义

Room temperature; ambient temperature; normal temperature. The ordinary temperature of the surrounding environment, typically around 15–25°C.

A practical term used in science, medicine, food safety, and logistics to specify that something should be stored or used at room temperature — not refrigerated, not heated. Appears on product labels (常温储存 — store at room temperature), in scientific protocols, and in everyday speech when discussing beverages or food handling. Contrasts with 冷藏 (refrigerated), 冷冻 (frozen), and 高温 (high temperature).
