II. PRINCIPLES OF PERIODIC MEASURES

as a standard test gas, when nitrogen flows through the measured sample under a certain pressure action, the pressure difference is established at both ends of the sample △Pc, the gas flow is accurately measured by mass flow meter, and the core permeability is calculated by darcy's law for gathering other parameters.
