wavelength and the spacing between the surface atoms within the crystal x-rays similar to X-ray crystal as a diffraction grating space, i.e., when the beam of X-rays irradiated to the object, the object scattering by atoms, each atom scattering wave Alashan X-ray diffractometer, these waves interfere with each other, the result is a diffraction. The results of the strength of the diffracted wave superposition rays in some directions strengthened, weakened in the other direction. Diffraction analysis, the crystal structure can be obtained. The above is an important science in 1912 German physicist Laue (M.von Laue) proposed foresee Xi'an X-ray diffraction, was immediately confirmed by experiment. In 1913, British physicist Prague Sons (WHBragg, WLBragg) Laue discovered on the basis, not only successfully determined the crystal structure of NaCl, KCl, etc., also made famous as the diffraction-based formula - Prague equation : 2dsinθ = nλ. Pinhole method using a pinhole collimator three monochromatic X-ray light source for X-ray diffraction, the sample is irradiated onto the plate. According to film a different location to penetrate the pinhole method is divided into law and Backfire pinhole pinhole method. Pinhole method to get the whole circle of the diffraction pattern diffraction lines Hailar X-ray diffractometer, suitable for study grain size, crystal perfection, macroscopic residual stress and polycrystalline samples of preferred orientation and so on. However, this method can only record very few diffraction rings, suitable for other applications. § has the following binding innovation? Transmission diffraction geometry technology. ?
