The three-dimensional space of atoms is arranged in a long-range order, and the smallest unit of repeated arrangement is called the cell, which can be divided into 7 kinds of crystal systems, 14 kinds of lattice, and 230 kinds of space groups according to the arrangement law.

The main indicators of polymer materials include the type of polymer or its crystallinity. Polymers also exhibit different microstructure, which can also affect the mechanical .properties of polymer materials.

X-ray diffraction (XRD) is a means of research to obtain information such as the composition of a material, the structure or form of an internal atom or molecule by analyzing its diffraction pattern through X-ray diffraction.

Dandong Tongda TD-5000X-ray single crystal diffractometer won the "ACCSI2023 Instrument and Detection 3i Award --2022 Annual Scientific Instrument Industry Outstanding New Product Award".

It is a professional manufacturer of X-ray analysis instruments and non-destructive testing instruments, and has obtained a number of certifications such as national high-tech enterprises, ISO quality system certification enterprises, and has an invention patent and utility model patent.

Crystals, although long admired for their regularity and symmetry, were not studied scientifically until the 17th century. Let's take a look at the early history of crystallography.

An important indicator of XRD is that there is a very good X-ray light source. The so-called good X-ray light source usually refers to high intensity, high parallelism and high purity. This paper will introduce one of the core technologies of neo-Confucianism, CBO optical path.

Using the principle of X-ray diffraction, the cutting Angle of natural and artificial single crystals is accurately and quickly determined, and the cutting machine is equipped for directional cutting of the said crystals.

The method of assisting internal stress without additional energy proposed in this paper provides an economical and convenient new strategy for improving battery reaction dynamics.

X-ray diffraction technology is widely used in the research of lithium-ion batteries. XRD is a conventional method for qualitative and quantitative analysis of phases in materials.

The WBK-01 X-ray system produces high-energy X-rays to irradiate cells or small animals. For a variety of basic research and applied research.
