严格说来, “0”不是汉字,因为汉字是方块字,由笔画组成,而“0”是无法分析笔画的,它没有笔画的起迄,无法分解出更小的单元,但是现在的《新华字典》和《现代汉语词典》又都收了“0”,归入“难检字笔画索引”的一画下,注释为“数的空位(同零),多用于数学中:三○六号、一九九○年”。可见,“0”既是一个汉字,又是一个数词。 Strictly speaking, “0” is not a Chinese character, because Chinese characters are square words and are composed of strokes. “0” cannot analyze strokes. It does not have the beginning and end of strokes, and can not be decomposed into smaller units, but now the Xinhua Dictionary “” and “Modern Chinese Dictionary” have all received a “0” and were placed under a picture of “Difficult-to-Pick Stroke Index.” Note: “The number of vacancies (same as zero) is used in mathematics: No. 306, 1990.” It can be seen that “0” is both a Chinese character and a numeral.
