Origin软件数据处理（寻峰和拟合）
以夫兰克-赫兹实验为例，仅供参考。
1. 将实验数据Excel表格导入到worksheet中

2. 选中A（X）和B（Y），单击右键，plot line+symbol，选择合适的样式作图。

![](https://wkrtcs.bdimg.com/rtcs/image?w=456.00&md5sum=9479d76688da950d9729267408e41754&sign=0eef98a37a&rtcs_flag=2&rtcs_ver=4&l=webapp&bucketNum=197&ipr={"t":"img","r":"r_8","w":"456.00","h":"341.33","dataType":"gif","c":"word/media/image3.gif"})
3. 对曲线进行拟合寻峰
a. 首先寻找baseline：找到下包络线，Analysis signal processing Envelope type: lower envelope，红线即为baseline
![](https://wkrtcs.bdimg.com/rtcs/image?w=550.96&md5sum=9479d76688da950d9729267408e41754&sign=0eef98a37a&rtcs_flag=2&rtcs_ver=4&l=webapp&bucketNum=197&ipr={"t":"img","r":"r_8","w":"550.96","h":"289.54","dataType":"jpeg","c":"word/media/image4.jpeg","imgOriW":1165,"imgOriH":515})
![](https://wkrtcs.bdimg.com/rtcs/image?w=461.33&md5sum=9479d76688da950d9729267408e41754&sign=0eef98a37a&rtcs_flag=2&rtcs_ver=4&l=webapp&bucketNum=197&ipr={"t":"img","r":"r_8","w":"461.33","h":"346.67","dataType":"gif","c":"word/media/image5.gif"})
b. 寻峰+拟合
Analysis Peaks and Baseline Peak Analyzer Fit Peaks (Pro)
Baseline mode Use existing Dataset 选择之前的下包络线
扣除baseline，Find peaks选项中调整Peak Filtering，找到6个峰。
Gauss拟合，确定6个峰位，利用逐差法和最小二乘法计算出Ar原子的第一激发电位。
