迷离（Blurred） Zip4-gj0f defines the diffraction of 1:X rays by the scattering of electrons outside an atomic nucleus. Since regular atoms are arranged in a crystal, regular diffraction patterns are used to calculate the distances and spatial arrangement of the atoms in the molecule. It is a useful method for analyzing the spatial structure of macromolecules. Subject: biochemistry and Molecular Biology (first level discipline), methods and techniques (two discipline) define diffraction of 2:X rays by the scattering of electrons outside the nucleus. Because the regular atomic arrangement in the crystal will produce regular diffraction images, it is possible to calculate the distances and spatial arrangement of various atoms in the molecule, which is a useful method for analyzing the spatial structure of macromolecules. Subject: Cell Biology (first level discipline), cell biology technology (two level discipline), this content is examined and approved by national science and technology term examination and Approval Committee, announce catalogue brief introduction principle Applied phase analysis Precise determination of lattice parameters Orientation analysis Introduction to recent developments principle Applied phase analysis Precise determination of lattice parameters Orientation analysis Latest progress Edit this paragraph Characteristic X ray and its diffraction X ray is a kind of electromagnetic wave with a short wavelength (about 20 ~ 0.06). It can penetrate a substance of a certain thickness, and can make fluorescent substances luminous, and photographic emulsion, photosensitive and gas ionization. The X target is produced by bombarding a metal target with a high-energy electron beam. It has a specific wavelength corresponding to the elements in the target, called characteristic (or marked) X ray. The wavelength of the X ray corresponding to the target material used generally Its 1.5406. Taking into account the wavelength and the crystal plane of atoms X ray in th
