METHOD AND PROGRAM FOR EVALUATING MOBILITY OF POROUS MATERIAL, AND PROGRAM RECORDING MEDIUM THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a method and a program for evaluating mobility of a porous material, which can obtain the mobility of the porous material and its pore size distribution at the same time, and to provide a recording medium therefor. SOLUTION: The method for evaluating the mobility of the porous material comprises a first step in which a prescribed range of data are assigned as object data to be processed from measurement data obtained by a magnetic field gradient NMR method; a second step in which the object data are used to obtain parameters in a distribution function of diffusion coefficients by using an iterative method so that the object data are reproduced by calculation values calculated using an expression including the distribution function; a third step in which the calculation values from the above expression are compared with corresponding object data by using the obtained parameters, and reproducibility of measurement data from the expression is evaluated; and a fourth step in which a determined average value and a width value of the distribution function are presented.
