Lloyd et al, 1912 According to the theory predicted and experimentally confirmed the encounter can occur when the X-ray diffraction and X-ray diffraction crystal Kunming prove that X-rays with the nature of electromagnetic waves, the first milestone in the X-ray diffraction studies. When a monochromatic X-rays incident on the crystal, the crystal is composed of atoms in a unit cell arranged in the rules, the rules are arranged in the interatomic distance between the X-ray wavelength of the incident X-ray diffraction analysis of the same magnitude, the scattered by different atoms The X-rays interfere with each other Tongcheng X-ray diffraction, resulting in a strong position and intensity of X-ray diffraction, the spatial distribution of the diffraction lines in some particular direction, closely related to the crystal structure. This is the basic principle of X-ray diffraction. Relationship between the spatial orientation of the diffraction lines of the crystal structure is available Bragg equation: 2dsinθ = nλ where: λ is the wavelength of X-rays; θ is the diffraction angle; d is the crystal plane spacing; n is an integer. A known wavelength λ of X-ray diffraction angle measurement thus obtained spacing, i.e., atoms or ions in the crystalline ordered state. X-ray diffraction to determine the strength and surface interval table with known control sample to determine the crystal structure of matter, namely qualitative analysis. Comparison of X-ray diffraction intensity from the quantitative analysis can be performed. Monocrystalline and polycrystalline texture orientation determination of single crystal orientation is determined to find bits of crystal orientation of the crystal sample and the sample coordinate system to the outside relationship. Although it is possible to determine the orientation of the single crystal optically and other physical methods, but X-ray diffraction method can not only accurately oriented single crystal, but also get information inside the crystal microstructure. Laue method generally used single-crystal X-ray diffraction huoqiu orientation, based on the positional relationship between the polar stereographic projection polar stereographic projection axis with the sample outside Laue spots on the film to convert between. Transmission Laue method is only applicable to a small thickness and the absorption coefficient of the sample; Backfire Lloyd without special sample preparation method on X-ray diffraction, the size of the sample thickness, also not restricted, and they tend to use this method. ? Wireless transmission using WIFI wireless connectivity, remote control and transmission of the data collected, the timeliness of data acquisition and data processing site.
