摘要：

FIELD: physics.SUBSTANCE: using to determine the pore diameter of the porous object. Essence of invention consists in entering liquid gallium or one of the alloys in a liquid state and selected from the group consisting of gallium indium (Ga-In), gallium-tin (Ga-Sn) and gallium-indium-tin (Ga-In-Sn), into said porous object; measuring the nuclear magnetic resonance spectrum on the gallium nuclei in liquid gallium or in one of the alloys in the liquid state and selected from the group consisting of gallium indium (Ga-In), gallium-tin (Ga-Sn) and gallium-indium-tin (Ga-In-Sn), in said object with the Knight Shift determination (K) from the NMR spectrum obtained; measuring the nuclear magnetic resonance spectrum on the gallium nuclei in liquid gallium or in one of the alloys in the liquid state and selected from the group consisting of gallium indium (Ga-In), gallium-tin (Ga-Sn) and gallium-indium-tin (Ga-In-Sn), with the Knight Shift determination (Kb) from the NMR spectrum obtained; determining the pore diamet
