    摘要: A simulation system (101) includes an X-ray CT device (11) that obtains a tomographic image of a porous sample, and a simulation device (14) that simulates a mercury intrusion method by processing a laminated tomographic image of the sample. The simulation device (14) includes a modeling means which processes the laminated tomographic image of the sample, and which models an internal structure of the sample, a minimum-diameter obtaining means that obtains a minimum entrance diameter when mercury enters in a pore of the sample at a predetermined pressure based on a surface energy of the sample and a pressure, and a means that simulates a liquid entering in the interior of the pore from one surface of the sample based on a diameter of the pore of the modeled sample and the minimum entrance diameter.
