The X-ray intensity of nondestructive testing at a point in space is the sum of the number of photons and the energy product over a unit area perpendicular to the X-ray propagation direction in unit time.

Biological X-ray irradiator irradiates organisms with high-energy rays with ionizing radiation effect within a predetermined time, producing biological effects or suffering irreversible damage and destruction to achieve biological purposes.

In the field of NDT, there are mainly two detection methods: industrial CT detection and X-ray detection, both of which use X-rays to detect the interior of the object.

X-ray diffraction technique is widely used in drug analysis. X-ray diffraction technique is an analytical method used to study the structure of a substance. This technique has many applications in drug analysis.

In order to show the good style of Dandong Tongda Company's vigorous development, enhance friendship and enhance cohesion, the company organized a group building activity from January 30 to 31, 2024.

The stronger the light, the brighter? But this is not always the case. When the intensity of the X-ray beam begins to exceed a certain critical value, the diffraction image unexpectedly weakens.

Powder X-ray diffraction, as one of the methods for the study of drug polymorphism, has the advantages of no sample destruction and simple operation.

SBA-15 is a mesoporous silicon-based molecular sieve with a highly ordered hexagonal straight pore structure (p6mm), the pore size can vary from 5 to 50 nm, and the pore wall is thicker.
