摘　　要：采用origin软件对不同灯丝电压对氩原子第一激发电位的数据处理。通过绘制IP-UG2曲线图以及对IP-UG2曲线图进行求导,能够合理的找到峰、谷值,数据处理比较简洁。通过计算可知,当灯丝电压为2.9 V时实验得到的氩原子第一激发电位为U=12.15 V,和理论值比较接近,误差较小。The origin software was used to process the data of the first excitation potential of argon atoms at different filament voltages.By drawing-curve diagram and differentiating-curve diagram.The peak and valley values can be reasonably found,then data processing is relatively simple.When the filament voltage was 2.9 V,the first excited potential of the argon atom was 12.15 V,which was obtained in the experiment.The value was close to the theoretical value and a small error.
