2 作者: Li, Yuanlu 来源出版物: Anal Bioanal Chem 卷: 394 期: 2 页: 637-45 出版年: 2009 May [PubMed 相关文章] 摘要: Using the Tsallis distribution, which facilitates the generalization of well-known distributions such as Gaussian and Lorentzian by varying a non-extensivity parameter q as a model of the individual band to correctly assign overlapping bands and the fractional differentiation as mathematical tool to help to determine the spectral parameters of the individual band, a new resolution method for the overlapping bands is presented. According to variation of the maximum and the zero-crossing of the Tsallis distribution at different differential order, two types of parameter estimators are obtained, which are utilized to calculate the parameters of position, height, and width of Tsallis distribution. To verify the suggested method, separation of several kinds of overlapping bands simulated by computer and the experimental infrared spectrum of 1,2-bromofluoroethane have been performed and discussed.

1 作者: Li YL (Li YuanLu), Yu SL (Yu ShengLin), Zheng G (Zheng Gang) 来源出版物: SCIENCE IN CHINA SERIES B-CHEMISTRY 卷: 50 期: 6 页: 797-805 出版年: DEC 2007 被引频次: 1 参考文献: 14 引证关系图 摘要: Equations between the differential order and the maximum of the fractional-order differential for the specified peak signals are developed based on the variation of the maximum of the specified peak signals at different orders. Also, equations between the differential order and the zero-crossing of the fractional-order differential of the specified peak signals are proposed according to the variation of the zero-crossing of the specified peak signals at different orders. Characteristic parameters of the Gaussian peak, Lorentzian peak, and Tsallis peak can be estimated using estimator I and estimator II which are obtained by the equations above. As a result, a new method is presented to resolve the overlapped peaks signal. Firstly, a fractional-order differential of the specified peak signals is obtained with the fractional-order differentiation filter. Then, characteristic parameters of the specified peak signals can be extracted using estimator I and estimator II. Finally, the Tsallis peak is used as a model to assign the overlapping peak signals correctly. Experimental results show that the proposed method is efficient and effective for the simulated overlapping peaks and detected overlapping voltammetric peak signals. 文献类型: Article 语言: English 作者关键词: fractional-order differentiation filter; fractional-order differential; overlapping peaks; voltammetric peak 通讯作者地址: Li, YL (通讯作者), Nanjing Univ Informat Sci & Technol, Coll Informat & Control, Nanjing 210044, Peoples R China 地址: 1.
