Subject is focused on issues concerning determination of the porous material texture properties including description of gas transport in porous solids. Basic characterization and description of the porous material texture properties by the physical sorption of inert gases, mercury porosimetry and helium pycnometry belongs to the main topic of this subject. The integral part is also application of theoretical knowledge for evaluation of the real data of porous solids with pores in the range from 0.3 nm to 100 m.
