method for determining an appropriate size for a representative sample of a heterogeneous material, system for determining an appropriate size for a representative sample of a heterogeneous material, and method for determining an appropriate size for a representative sample of a heterogeneous underground rock formation

摘要

method for determining an appropriate size for a representative sample of a heterogeneous material, system for determining an appropriate size for a representative sample of a heterogeneous material, and method for determining an appropriate size for a representative sample of a heterogeneous underground rock formation concerned refers to methods for determining representative element areas and volumes in porous media. Representative element area (rea) is the smallest area that can be modeled to yield consistent results within acceptable bounds of the model property's regression. porosity and permeability are examples of such properties. In 3d, the appropriate term is representative element (rev). rev is the smallest volume of a porous medium that is representative of the measured parameter.
