中文摘要：

从对分压偏置共射极放大电路进行静态分析时存在的问题出发，介绍了静态分析常用的三类方法，包括估算法、戴维宁定理等效计算法和基尔霍夫两定律求解法．通过三类方法的比较，提出了选择估算法需满足的一个相对简单又直观的条件，并指出了戴维宁定理等效计算法和基尔霍夫两定律求解法没有使用条件的限制，为电类专业和非电类专业的教学与学习提供了参考．

英文摘要：

From the problem in static analysis to a kind of voltage-divided bias common emitter amplifier circuit, introduced three methods commonly used, including estimation method, Thevenin＇s theorem equivalent calculation method and the solution method based on the two Kirchhoff＇s law. By comparing the three methods, a simple and visual condition to be met has been proposed when estimation method is selected. It has also put forward that Thevenin＇s theorem equivalent calculation method is suitable for electrical specialty learners and the solution method based on the two Kirchhoff＇s law is suitable for non-electrical specialty learners, meanwhile there has no limitation in using of the two methods. The teaching reference was provided to the teachers engaged in the teaching of electrical specialty and non-electrical specialty.
