摘要：

The X-ray radiation passage through randomly arranged narrow (submicron) channels in a solid was studied by the method of numerical modeling taking into account the diffraction and reduced coherency effects. It was found that the X-ray transmission is markedly deteriorated in the channels subject to periodic deformation. The randomization effects are interpreted within the framework of the statistical theory of X-ray scattering in a rough transitional layer. An anomaly in the energy dependence of the X-ray transmission through a thin (1620 Angstrom) Cr/C/Cr channel observed for a 17 keV mode is explained by small periodic bending perturbations and related interferences in the structure.
