摘要: Abstract All methods presently employed for pore structure analysis are based on idealized models the shapes. Most investigators assume that pores cylindrical; some use parallel plate model. The extent to which valid inferences can be drawn from curves such idealizations is open question. A method presented by volume and surface distributions obtained without assuming any shape pores. made in terms of hydraulic radii instead Kelvin radii; radius being defined as V S , where a group area walls. conventional manner adsorption or desorption isotherms; also isotherms, new method. volumes, surfaces, thus properties cores pores; core empty part contains an adsorbed film its relationships between discussed.
