In folklore, "磷火" refers to "ghost fire" (phosphorescence), linking phosphorus with mysterious nighttime lights.
• 常见用法及易混淆点：“磷”常用于化学、医学、农业等领域，如“磷酸”（phosphoric acid）、“磷肥”（phosphate fertilizer）、“磷脂”（phospholipid）。易与“麟”（指麒麟）、“鳞”（鱼鳞）等字混淆。 Common usage & confusing points: "磷" is commonly seen in chemistry, medicine, and agriculture, e.g., "磷酸" (phosphoric acid), "磷肥" (phosphate fertilizer), "磷脂" (phospholipid).
