The energy spectrum estimation device 92 calculates an X-ray energy spectrum by dividing, by the normalized modified efficiency matrix, the particular result obtained by the Bayesian estimation equation.Takagi HiroyukiMurata Isao
energy dispersive x-ray spectrum 的意思是：能量色散X射线光谱
从不粘炊具涂层到薄膜电子和生物活性表面,X 射线光电子能谱是进行表面表征的标准工具之一。 X 射线光电子能谱 (XPS) 也称为用于化学分析的电子能谱 (ESCA),是一种用于分析材料表面化学的技术。XPS 可以测试得到材料表面元素组成及化学态信息。通过使用一束 X 射线照射固体表面并测量从材料表面 1-10 nm 发射的...
在对材料进行表征时,我们可以通过形貌观察获得材料的结构信息、通过元素分析获得材料的成分信息。X射线能谱仪(Energy Dispersive X-ray Spectroscopy,EDS)简称能谱仪,是扫描电镜进行元素分析的重要附件。它通过判别特征X射线的能量对材料的成分进行定性和定量分析,面分布技术还可以提供元素空间分布的信息。扫描电镜与能谱...

dispersive X-ray spectroscopy, the gas proportional counter has been largely superseded by the cryogenic semiconductor (Ge or Si) detector which can give a FWHM energy resolution down to the order of 150 eV; some five or so times better than that of the gas counter in the few-keV energy ...
有效X射线能量(effective x-ray energy)是将多色 X 射线的能量表示为具有等效相互作用的单色 X 射线的能量,有效 X 射线能量通常用作多色 X 射线光子能谱的代表值。 具体来说,有效能量是使用由铝(Al)或铜(Cu)组成的吸收体来测量的。 在大约 65keV-70keV的虚拟单能量图像(virtual monochromatic image,VMI)上...
