从线性空间映射的角度对相量法进行解析,并结合香农观点解析了相量法的本质,分析了如何用一个复数来表征一个正弦曲线,指出了正弦空间和相量空间(复数空间)的一一映射关系,在此基础上通过相量变换,将复杂的正弦函数运算转化为简单的复数运算,简化了正弦电路的微分方程的求解和正弦函数的计算过程.教学实践证明,应用这种解析方法加深了学生对相量法和相关概念的理解程度;更重要的是理解这种空间变换不仅有助于掌握相量法这个数学算法,更在于对创造性思维的启发.

We analyzed the phasor method based on linear mapping space combining with the views of Shannon to reveal its essence, meanwhile we explored the way to characterize a sine curve with a complex number, and proposed the one-to-one mapping relation between the sinusoidal space and phasor space. The cumbersome sinusoidal calculation was converted into the simple complex calculation, which simplifies solving differential equation of sinusoidal circuit and sine function; teaching practice proves that this analytic method improves the students' understanding level to the phasor method and related concepts; more importantly, understanding the transformation between the two spaces not only helps the students master the phasor method as a mathematical algorithms, but also inspires their creative thinking.
