    摘要: An X-ray analysis apparatus including an artificial multi-layered grating for rendering X-ray beams to be monochromatic before they are incident on a specimen to be analyzed. This artificial multi-layered grating operates to diffract the X-ray beam, generated from an X-ray radiation source and subsequently impinging on a reflective surface of the artificial multi-layered grating, at a predetermined angle of diffraction to provide the monochromatic X-ray beams. The periodicity of the spacing of lattice planes of the artificial multi-layered grating is so chosen as to be of a value progressively varying along the reflective surface thereof with an increase in distance from the X-ray radiation source. The X-ray analysis apparatus herein disclosed is designed to avoid any possible reduction of the intensity of the X-ray beams which would occur when they are rendered to be monochromatic, and to increase the intensity of the X-ray beams to ensure an improved accuracy in spectroscopic analysis.
