X射线在复合材料中辐射的散射研究
Scattering research for X-ray radiation internal composites material
摘要
Abstract
The Compton scattering phenomenon, the second--order radiation and multiple order radiation occur when X-ray transmitting into composites material. Based on Beer law of X-ray radiation, a quantitative relationship internal composites material between the first-order and second-order radiations is studied. The quantitative relationship internal composites material between the multiple order radiation intensity and the transmitting thickness is also obtained from the ray radiation intensity equation. The result shows that the radiation intensity has nothing to do with energy. According to radiation intensity differential equation in which the scattering photos tilt in same angle internal composites material, the scattering intensity equations of the multiple order ray and the general radiation intensity of X-ray transmitting parallel is derived.关键词
