摘　　要：从教学角度,利用构造思维,提出一种P变换与P-1变换,从而将正弦电路分析中正弦量与相量的抽象的"对应"关系转换为一种数学变换关系,并证明了这种变换的基本性质.进而利用这些性质建立起基尔霍夫定律,以及线性元件方程的相量形式.使得初学者能深刻理解相量法,降低学习难度.From perspective of teaching and by means of a constructive idea,this paper brings up both P-Transformation and P-1-Transformation,which are,during the sinusoidal circuits analysis,able to convert the Abstract connection between sinusoidal quantity and phasor into a kind of mathematics transformation,and show it true for some basic properties about P-Transformation.Furthermore,the phasor forms about Kirchhoff's laws and linear element equations are also completed through the use of the basic properties.All these make it doable for beginners to grasp the phasor method.

关 键 词：P变换 正弦量 相量
