摘　　要：论文主要讨论了三极管的工作状态以及三极管静态值对其放大倍数的影响。首先说明了三极管的类型及工作模式,继而讨论了三极管外置电阻的改变会对三极管静态值的影响,指出在平时使用三极管时应调整到合适的静态值以使其工作有额定的放大倍数。This paper mainly discusses the working state of triode and the influence of transistor static value on its amplification. Firstly paper introduces the type and working mode of the triode, and then discusses the influence of changing the triode externai resistance on the value of a static tube, pointes out that in the ordinary using triode, we should adjust it to the appropriate static values in order to make it work with rated magnification.
