The distinct parts of the X-ray absorption spectrum, namely the pre-edge region, the near edge (XANES) region, and the extended (EXAFS) region, provide complementary information about the local chemical environment of Cr. Analysis of the XANES and EXAFS spectra showed that the structure around...

X-ray检测 基本概念 X射线(又称伦琴射线、X-Ray)是 1895年德国物理学家伦琴在研究阴极射线时发现的一种射线,系高速运动的电子在与物质相互作用中产生的。在X射线管中,从阴极发射的电子,经阴极、阳极间的电场加速后,轰击X射线阳极靶,将其动能传递给靶上的原子,其中约有1%左右的能量转化为X射线,并从X射线照射...
