钙 🔊

网络内容摘要 (Web Content Summary):

钙（拼音：gài）是一个表示化学元素的汉字，指的是一种银白色、柔软的二价碱土金属（元素符号Ca，英文为calcium）。钙在自然界中主要以化合物的形式存在，比如碳酸钙（石灰石）、硫酸钙或磷酸钙等，广泛分布在矿物、岩石和水中。人体骨骼和牙齿的主要成分之一就是钙。 钙 (pinyin: gài) is a Chinese character meaning the chemical element calcium, a silver-white, soft, divalent alkaline earth metal (symbol: Ca). In nature, calcium usually exists as a compound, such as calcium carbonate (limestone), calcium sulfate, or calcium phosphate, found in minerals, rocks, and water. Calcium is essential for human bones and teeth.

• 字形构造： “钙”左为“钅”（金字旁，表示与金属相关），右为“盖”（音旁，表示读音），显示该字属金属类别，是现代化学元素名称中常见的构字方法。 Character structure: "钙" comprises "钅" (the radical for metal, indicating a metal element) on the left and "盖" (phonetic component, indicating pronunciation) on the right. This is a common pattern for modern chemical element names in Chinese.
• 常用词语： 如“钙片”（calcium tablets）、“补钙”（calcium supplementation）、“钙化”（calcification）。 Common words: Examples include "钙片" (calcium tablets), "补钙" (to supplement calcium), "钙化" (calcification).
• 易混淆： “钙”与“钴”（cobalt）、“钠”（sodium）等化学元素字形相似，都带有“钅”旁，注意区分。 Easily confused: "钙" is visually similar to other chemical element names like "钴" (cobalt), "钠" (sodium), etc., as they all contain the "钅" radical. Pay attention to the different phonetic components.
• 文化趣闻： “钙”作为近现代新造字，不见于古代文献和成语，专用于科学领域。 Cultural note: "钙" is a modern character, newly created for scientific use, and does not appear in ancient texts or idioms.
