|specific area;比表面積
Specific Surface Area（比表面積） 是描述物質表面積特性的重要參數，具體解釋如下：
定義
Specific Surface Area 指單位質量物質的總表面積，通常用于衡量固體材料（如粉末、多孔材料）的表面積分布特性。例如，1克材料的表面積若為100平方米，其比表面積即為100 m²/g。
單位與計算
常用單位為平方米每克（m²/g） 或平方米每千克（m²/kg）。計算公式為：
$$
text{比表面積} = frac{text{總表面積}}{text{質量}}
$$
對于多孔材料，表面積包括顆粒外表面和内部孔隙表面。
重要性
比表面積越大，物質與外界接觸的活性位點越多，直接影響其物理化學性質。例如：
測量方法
常用BET法（基于氣體吸附原理）測定，通過吸附氣體量推算表面積。
應用領域
涵蓋材料科學、化工、環境工程等，例如催化劑設計、藥物載體開發、空氣淨化材料研究等。
若需進一步了解測量技術或具體案例，可參考材料科學相關文獻或專業手冊。
