【摘要】 本文提出了一种新的计算多孔固体比表面积的方法。这个方法是根据氮气的脱附等温线求出单分子层饱和吸附量(V_m),然后求出比表面积(S_o)。用该方法的计算结果与用BET方法计算的结果相对误差很小。由于推导该方法需要的假设和近似比BET方程少,所以尤其在多孔固体的表面积测定中显示出它的结果正确性和优越性。更多还原

【Abstract】 This paper proposes a new method using isiothem of desorption of nitrogen to calculate the monolayer volume (Vm) and the special surface area (So) . The relative deviation between the results of calculation by this method and by BET requation is very small. As the assumptions and the approximations required for deriving in this method are less than those in BET equation, it can produce more accurate results than other methods in determining the surface area of porous solids.更多还原
