摘　　要：传统低频电路的分析方法无法适应于高频电路的研究,学生在学习时普遍感到难入门、模型抽象。本文采用对比的方法,介绍了从低频过渡到高频工作模式的转变、研究方式方法的差异。利用等效电路模型,将高频电路图转换成学生容易理解的低频电路图。从电路基本元器件、测量仪表、加工方式以及PCB的相关影响等方面介绍高频电路与低频电路在实际工程应用中的差异,将理论与实际工程运用相结合,加深学生对高频电路与低频电路内在差别的理解。The analysis method for the traditional low-frequency circuit cannot be adapted to the research of high-frequency circuit. Students generally find it difficult to start and feel model abstraction while studing. This paper introduces the transition from low frequency to high frequency working mode and the difference of research methods. In addition, using the equivalent circuit model, the high frequency circuit diagram is converted into a low frequency circuit diagram that is easy for students to understand. At the same time, the difference between high frequency circuit and low frequency circuit in practical engineering application is also introduced from the basic components of the circuit, measuring instruments, processing methods and related effects of PUB. Finally, the combination of theory and practical engineering will deepen students' understanding of the inherent differences between high-frequency circuits and low-freqency circuits.
