關(guān)于數(shù)值范圍的規(guī)范用法1.數(shù)值范圍的表示a.表示數(shù)值范圍應(yīng)用符號“～”.b.單位相同的數(shù)值范圍,只需在最后一個數(shù)值寫出單位符號,其余省略,但緊貼數(shù)值的角標(biāo)型單位符號不能省略;冪次相同的數(shù)值范圍以及采用百分號表示的數(shù)值范圍,每個數(shù)值的冪次或百分號不能省略;用萬、億表示的數(shù)值范圍，每個數(shù)值的萬、億不能省略.例如:2～30 mol/L;100°～180°;2×104～7×104;(2～7)×104km;50%～80%;2萬～10萬.c.采用公差形式表達(dá)的數(shù)值范圍
