XRD is a means of research which is Diffraction by X-Ray diffraction of a material to analyze its diffraction pattern to obtain information such as the composition of the material, the structure or shape of atoms or molecules inside the material.

Grazing-incidence X-ray diffraction (GI-XRD) is a kind of X-ray diffraction technique, which is different from the traditional XRD experiment, mainly by changing the Angle of X-ray incidence and the orientation of the sample.

It is necessary to reduce the harmful residual stress and predict the distribution trend and value of residual stress. In this paper, the non-destructive testing method of residual stress testing is introduced.

X-ray diffraction (XRD) is currently a powerful method for studying crystal structure (such as the type and location distribution of atoms or ions and their groups, cell shape and size, etc.).

X-ray crystallography is a technique used to determine the atomic and molecular structure of a crystal, where the crystal structure causes the incident X-ray beam to diffract into many specific directions.

Based on Bragg's Law, in-situ X-ray diffraction (XRD) can be used to monitor the change of phase and its lattice parameters in the electrode or electrode-electrolyte interface in real time during the charge-discharge cycle of a battery.

Three single point detectors are shared below: proportional counter, scintillation counter, and semiconductor solid state detector.

X-ray diffraction, through the X-ray diffraction of a material, the analysis of its diffraction pattern, to obtain the composition of the material, the structure or shape of the atoms or molecules inside the material and other research means.

X-ray diffraction is the most effective and most widely used means, and X-ray diffraction is the first method used by humans to study the microstructure of matter.

X-rays are a type of short-wavelength electromagnetic radiation, between ultraviolet and gamma rays， that was developed by the German physicist W.K. It was discovered by Roentgen in 1895, so it is also called Roentgen rays.

When X-ray diffraction is projected into a crystal as an electromagnetic wave, it is scattered by the atoms in the crystal, and the scattered waves appear to emanate from the center of the atoms, and the scattered waves emitted from the center of each atom are similar to the source spherical waves.
