摘　　要：本文从分析直流放大器和交流放大器的区别入手,对二者相关的概念和特点进行研究,其中重点叙述了它们的五个不同点即:放大信号不同,输入、输出、级间耦合方式不同,出现问题不同,电路特点不同,特点不同,以便于学生在学习的过程中,明辨它们的区别,能够有针对性地学习、掌握。From the differences between direct current amplifier and alternating current amplifier, this paper made a research on their related concepts and features. Five differences between them such as the different enlargement object, the different input, output and interstage coupling way, different problems, different forms of electric circuit, and the different features. This will be helpful for the students to distinguish them and mater their differences.
