摘　　要：针对同相比例运放电路,以测定电路的放大倍数为研究对象。用非等精度测量方案获取原始数据,用SPSS曲线估计功能处理样本数据,得到系统输出电压量与输入电压量的关系曲线,验证得电路输出电压与输入电压存在线性关系,由此标定出同相比例运放电路的放大倍数。用置信概率为95%不确定度去评价实验数据及结果,最终得到更加直观、合理的结果。According to the same-phase proportional operational amplifier experiment device,measuring the amplification factor of the circuit is designed to the research object.The measurement data are obtained by the way of non-equal precision measurement.Using the linear estimation function of SPSS is to analyze the experimental data.Its aim is to get the output and input voltage calibration curve and to verify the linear relationship between output and input voltage.The result is that the coincident proportional amplification multiples are obtained.At the same time,using confidence probability of 95% is to analyze and evaluate the measurement data and experimental results.According to above procedures,the research can get more reliable and reasonable results.
