Design And Implementation Of Analytical Software For Electrochemistry

In recent20years, electrochemistry analytical instruments have been greatly developedat home and abroad, and been widely used in research and industrial fields, as well as thecorresponding analytical software. Many foreign instrument manufacturers have releasedpowerful analytical software in succession. In contrast, the development of analyticalsoftware is slow domestically, with analytical functions being simple and low efficiency incase of large amount of data. Therefore, to develop software supporting high effectiveplotting and diversified electrochemical analysis is of practical value.In this thesis, the background of electrochemical analysis software is briefly introduced.An new analytical software Corshow was designed, which supports fast plotting and analysisfor polarization and voltammetric curves. The software framework, design andimplementation of each module are illustrated at length in following chapters.This software is subject to the routine of object-oriented programming and consists offour parts: file management, graph, data analysis and help subsystem. The file managementis focus on accessing the project in serialization mode and parsing the data files in severalformats. Graph module is based on GDI+and optimized by filtering points supporting otherfunctions such as zooming, print and copy etc. The services provided by data analysismodule include data smoothing and filtering in Savitzky-Golay algorithm, fitting theelectrochemical kinetic parameters of polarization curves in Levenberg-Marquardt algorithm,calculating corrosion rate, recognizing the current peak in volt-ampere curves and analyzingthe height of peak automatically. Help system enables switching between Chinese andEnglish interfaces, and realizes bonding the documentation to different help themes.
