PeakFit、1stOpt在弗兰克-赫兹实验数据处理中的应用
|
摘要
引入了两种新的弗兰克-赫兹实验数据处理方法。1.运用峰值分析软件PeakFit实现数据的拟合与自动寻峰。2.通过数学优化软件1stOpt实现多峰与单峰拟合,然后编写1stOpt求最值程序获得其峰值信息。PeakFit操作简单,无需编程,多峰拟合效果良好,峰值信息精确。1stOpt获得的相关系数可达0.999 9,拟合效果极好,峰值信息准确可靠。
Two data processing methods of the Frank-Hertz experiment are proposed.First,the processing of data fitting and peak searching were achieved using the PeakFit software.Second.The single or multiple peak fitting can be achieved by the mathematical optimization package 1 stOpt,then we need making a simple 1 stOpt code,the location of the maximum value about peaks can be obtained.The operation from the PeakFit is very simple,without programming,it also can employ a variety of functions,and can get a better fitting result and accurate peak information.The correlation coefficient between experiment and fitting is close to 1 if we apply the1 stOpt,the fitting result is excellent,peak information is accurate and reliable.
