摘　　要：通过Multisim10.1软件对高频小信号单调谐放大器的仿真分析,观察到了发射极电阻的变化对单调谐回路频率特性的影响。利用实例证明:将Multisim10.1引入高频电路实验教学后,该软件能及时帮助学生理解课程内容、提高学生分析问题和解决问题的能力,Multisim10.1软件在"高频电子线路"课程教学改革中起着越来越重要的作用。For the single tuned amplifier of small signal with high frequency, the analysis and simulation have been carried through using Multisim 10.1 software. The influence of the change of the emitter resistance on the frequency characteristics of the single tuned circuit has been observed. By using actual examples, after introducing Multisin 10.1 in the experimental teaching of high-frequency circuit, this software can help students understand the Course contents, and improve the students abilities to analyse issues and solve problems, which shows that Multisim 10.1 software plays an increasingly important role in teaching reform of the high- frequency electronic circuit.
