请问比表面和孔径孔容到底应该看哪个啊?

感觉数据很奇怪,t-Method Micro Pore Volume..................................  0.000E+00  cc/g??
为什么比表面积还很大啊?
比表面积BET和Langmuir怎么差别这么大?
有没有等温线的数据?
孔容可以用这个:
Total Pore Volume for pores with Diameter
less than 5043.8 Å at P/Po = 0.99622........................  6.043E-01  cc/g

是做的一种介孔(mesoporous)材料吧,不像是活性炭。

t-Method Micro Pore Surface Area............................  0.000E+00  m²/g
BJH Interpolated Cumulative Adsorption Pore Volume for pores
in the range of 5000.0 to 0.0 Å Diamater....................  6.026E-01  cc/g
BJH Interpolated Cumulative Desorption Pore Volume for pores
in the range of 5000.0 to 0.0 Å Diamater....................  6.200E-01  cc/g

最好看图。
