In recent years, X-ray small Angle scattering technique of biological macromolecules has been widely paid attention to. This article will mainly introduce the relevant progress of the combination of biological small Angle and other techniques in recent years.

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.

Nondestructive testing is based on the development of modern science and technology. With the development of modern industry, the application of non-destructive testing is more and more popular.

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.

X-rays are a type of electromagnetic radiation widely used in medical and industrial fields. Although most X-rays are produced artificially, there are also some phenomena in nature that produce X-rays.

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.

X-ray testing is a non-destructive testing method that does not damage the object itself, and has been widely used in material testing (QC), failure analysis (FA), quality control (QC), quality assurance and reliability (QA/QC), research and development (R&D) and other fields.

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