Abstract:
1. A non-uniform density sample analyzing method comprising: calculating a simulated X-ray scattering curve under the same condition as a measurement condition of an actually measured X-ray scattering curve by using a scattering function which represents an X-ray scattering curve according to a fitting parameter which indicates a distribution state of particle-like matter; and carrying out fitting between the simulated X-ray scattering curve and the actually measured X-ray scattering curve while changing the fitting parameter, wherein the value of the fitting parameter when the simulated X-ray scattering curve agrees with the actually measured X-ray scattering curve serves to indicate the distribution state of the particle-like matter in a non-uniform density sample, thereby analyzing the distribution state of the particle-like matter in the non-uniform density sample, wherein the actually measured X-ray scattering curve is an in-plane X-ray scattering curve obtained by in-plane diffraction measurement, wherein the fitting is carried out between the in-plane X-ray scattering curve and the simulated X-ray scattering curve, and wherein the value of the fitting parameter when the simulated X-ray scattering curve agrees with the in-plane X-ray scattering curve serves to indicate the in-plane direction distribution state of the particle-like matter in the non-uniform density sample.
