With the proper choice of K and L spectral lines, it is possible to improve the calibration curves, detection limit and sensitivity of the elements 19 ≤ Z ≤ 92. In the present work, the detection limit and sensitivity is studied by high advanced wavelength dispersive (WD) spectrometer. ...
1、The Fizeauwavemeter has wide range of application in laserspectralfields.(在激光光谱学领域中有着广泛的应用前景。) 2、Each pattern stands for a distinct chemical element, and so different sets or patterns ofspectrallines mean that the star has a different chemical composition.(每一种样式代表一...
In the article, a two-stage method of non-photorealistic rendering is presented. In the first stage, short segments of straight lines described by vectors and tangential to the object contours are generated. On this basis, a vector image is created with the use of vector space of increments....
Noun1.fine structure- the presence of groups of closely spaced spectrum lines observed in the atomic spectrum of certain elements; "the fine structure results from slightly different energy levels" spectrum line- an isolated component of a spectrum formed by radiation at a uniform frequency ...

Elements of modernism, spectral music and electronic music are combined with elements of the folk music of Eastern Europe and the resulting works are often influenced by the modality of Indian ragas. 現代主義元素、光譜音樂(英语:Spectral music)和電子音樂與東歐民間音樂元素相結合,產生的作品亦往往受到...
Study on the shielding of interferential gamma-rays in neutron element analysis 中子元素分析中干扰γ射线屏蔽研究 2. ICP-OES is a simple and rapid method in element analysis. 分析速度快,每个样品仅需时2～3min;检出限低,多数可达5ng/mL以下;测量动态线性范围宽,可达5～6个数量级,可同时进行高含量...
