摘要: We present a simulation study to investigate the significance of connectivity on adsorption isotherm, for collection connected pores. By examining different sequences in set three cylindrical sections sizes, we have been able obtain isotherms with variety shapes and sizes hysteresis loop; none which can be reproduced by combining individual pores two open ends. conclude that there is need re-examine choice kernel determination pore size distributions systems interconnected spaces.
