可见,最早“spectrum”是指光强和频率或波长的关系,后来“spectrum”才被扩展到其他是能量或荷质比函数的连续变量。 彩虹 由于XRD数据中,衍射强度是d值(或者2theta,sin(theta),Q等)的函数,他们均为空间尺寸相关的量,因此XRD结果图准确的叫法应该是“图案”或“pattern”,而不是"谱",只是现在文献里使用"谱"的越...

X-ray spectrum analysis is an element analysis of the material on the basis of its x-ray spectrum. From:Encyclopedia of Materials: Science and Technology,2001 About this page Add to MendeleySet alert Chapters and Articles You might find these chapters and articles relevant to this topic. ...
However, the energy resolution is not perfect, and a characteristic X-ray spectrum appears like a Gaussian curve with a half-width of several tens of electron volts. Due to this low energy resolution, an EDS often cannot discriminate between two characteristic X-ray lines of close energy or ...
The scientists analyzed archival X-ray data taken by Chandra and discovered an unusual dip in the ULX's X-ray spectrum, which is the intensity of X-rays measured at different wavelengths. After ruling out other possibilities, they concluded that the dip was likely from a process called cyclot...
