摘　　要：在线性电路中,利用傅里叶级数把电源产生的非正弦周期电压分解为一系列不同频率的正弦电压,分别计算在一种频率的正弦电压单独作用下一个电路元件上的电压分量,再根据叠加原理对所有电压分量进行叠加,从而得到这个电路元件上的实际电压。这就是工程技术中经常采用的谐波分析法。In a linier electric circuit, a non-sine cyclic voltage created by electric source can be divided into a series of sine voltages with different frequencies depending on the application of Fourier series. We can calculate the voltage element on one electric circuit unit acted separately by a single sine- voltage and add all the voltage elements together on the base of addition principle. Thus the real voltage on this electric circuit unit is obtained. This is the harmonic wave analysis method ordinarily used in engineering and technology.
