| Abstract: | On the basis of the physical behavior of x-ray fluorescence, the relationship of fluorescence intensity with pulse counts, that of fluorescence intensity with scattering intensity and that of scattering intensity with pulp density, as well as the inherent absorption law for x-rays are described in detail. A theoretical calculation formula of scattering intensity and fluorescence intensity is derived. The calculation method with iteration used on computer and block diagrams of programme are introduced. |
