Construction method and device of pore adsorption density model, terminal and storage medium

The invention provides a construction method and device of a pore adsorption density model, a terminal and a storage medium. The method comprises the following steps: calculating corresponding pore adsorption density according to defined pore diameters of different pore wall materials by utilizing a molecular simulation technology, and defining the pore adsorption density as first pore adsorption density; obtaining effective apertures obtained by calibrating different hole wall materials based on standard helium, and obtaining a mapping relation between the defined aperture and the effective aperture of each hole wall material; obtaining the pore adsorption density of the corresponding pore wall material according to the defined pore diameter corresponding to each pore wall material, the first pore adsorption density and the effective pore diameter, and defining the pore adsorption density as a second pore adsorption density; and constructing a pore adsorption density model of the different pore wall material
