摘　　要：以光电效应中"光电管伏安特性曲线的测定"为例,介绍了Origin软件在确定实验极值方面的一些特殊应用。结果表明利用该软件处理物理实验数据能大大减轻学生繁杂的数据计算及绘图步骤,有效避免了手工处理所带来的误差,并且能准确直观地获取手工方法难以得到的实验极值。Taking the experiment named the measurement of volt-ampere characteristic curve of photoelectric tube as an example,this article simply described some special applications of Origin in college physics experiment. The results showed that Origin could greatly lighten the complicated data processing burden of students,effectively avoid the error of manual handling,and deal with the experimental data accurately intuitively. Especially,it can obtain any limit values of experiment more direct and accurate than manual method. Origin is suitable for college physics experiment.
