核

• 拼音: hé
• 汉字拆解: 核 = 木 (wood/tree radical) + 亥 (phonetic; 12th Earthly Branch)

含义

Core; nucleus; kernel. The central, essential, or most critical part of something. Also: nuclear (as a prefix in scientific and military contexts).

As a standalone morpheme and word, 核 encompasses the literal sense of a seed or fruit stone, the biological nucleus of a cell, the nucleus of an atom (hence 核能, 核武器), and the figurative core of a system, argument, or leadership structure (核心). Its versatility makes it one of the most productive morphemes in modern Chinese scientific and political vocabulary.

例句

3. 核裂变所释放的巨大能量，既可以用于发电造福人类，也可能被制成毁灭性武器。
