Specific surface area
Mandarin:
比表面积
比表面积
Explanation in English Language (EN):
The surface area of a material per unit mass, often expressed in square meters per gram (m<sup>2</sup>/g). It's an important factor in catalysis and adsorption, as it determines the amount of surface available for reactions to occur. Materials with high specific surface areas, like porous materials or nanoparticles, are often used in catalysis and filtration.

Explanation in Mandarin (ZH):
单位质量物质的表面积，通常以平方米每克 (m<sup>2</sup>/g) 表示。它是催化和吸附中的一个重要因素，因为它决定了可用于发生反应的表面积量。具有高比表面积的材料（如多孔材料或纳米颗粒）通常用于催化和过滤。(Dān wèi zhì liàng wù zhì de biǎo miàn jī, tōng cháng yǐ píng fāng mǐ měi kè (m<sup>2</sup>/g) biǎo shì.
