adsorption surface area的用法和样例：
- The hard outer portion or surface area of bread.
- The BET surface area of CA could achieve 340.1m2/g.
- The pore size and specific surface area of ACFs were decreased after fluorination.The adsorption isotherm of nitrogen on ACFs were evidently reduced.
- The adsorption of s urfactant on the grain stabilized the fine grain, led to increasing the specific surface area and promoting the rate of reaction.
