摘要
利用MATLAB软件的命令行编程、一维离散小波的工具箱GUI功能和Simulink仿真三种方式,以电位滴定曲线为例,分别对电化学滴定曲线进行导数变换,以提高仪器检出信号和曲线突跃点确定的精度,为电化学定量检测提供一种有效的方法。此三种导数变换方式可以应用于一些基础电化学仪器的定量分析,尤其是对未配备相关计算软件的读数型电位滴定仪十分有效。本文所介绍的例程、例举可使电化学工作者在进行相关参数设置或导入、导出设定后直接应用到电化学分析实际工作。
Taking potentiometric titration curve as an example,the titration curve of electrochemistry is transformed into derivative curve by using command window program,wavelet 1-D of wavelet boxes and Simulink.It offers good methods for quantitative determination of electrochemistry to improve signal-to-noise and precision of leap-point of curve.These methods of derivative transformation may be applied to quantitative determination of basic electrochemistry instrument,especially in digital potentiometric titrator without software,which is quite effective.The analyzers of electrochemistry could apply examples of this paper to actual works directly after parameters are set up,import or export.
