补充资料：相量法
| 相量法 phaser method 分析正弦稳态电路的便捷方法。它用称为相量的复数代表正弦量，将描述正弦稳态电路的微分（积分）方程变换成复数代数方程，从而简化了电路的分析和计算。该法自1893年由德国人C.P.施泰因梅茨提出后，得到广泛应用。相量可在复平面上用一个矢量来表示（见图1）。若相量乘上ejwt（j＝  ），则表示该相量的矢量以角速度ω绕原点反时针旋转，于是得到一个旋转矢量，称为旋转相量（图2）。它在任何时刻在虚轴上的投影即为正弦量在该时刻的瞬时值。引入相量后，两个同频率正弦量的加、减运算可以转化为两个相应相量的加、减运算。相量的加、减运算既可通过复数运算进行，也可在相量图上按矢量加、减法则进行。正弦量与它的相量是一一对应的，因此求出了相量就不难写出原来需要求的正弦量。
