The phase method means that the voltage and circuit are expressed as phase, and the RLC components are expressed as resistance or admittance, then the phase model of the circuit are sketched out, the algebraic equation of unknown voltage and circuit phase are written out with the phase formation of KCL, KVL and Ohm`s law. Through the introduction of the phase method, and set up the definitions of resistance and admittance, the author gives out the phase formation of KCL, KVL and Ohm`s law, for their forms are entirely the same as that of the formula used in analysis of direct circuit, we can analyze the phase model of sinusoidal circuit directly using the methods, principles, laws that used in analysis of direct circuit, for example, the net hole method, the method of joint, the superposition theorem, Thevenin's theorem, the equivalent source theorem. The differences lie in:（1）Express all the relations without citing the instantaneous expression of voltage and current, but as the forms of corresponding phases; （2） The corresponding calculations are not algebraic calculations but plural calculations, so the calculations are more difficult than those of the direct circuits.
所谓相量法，就是电压、电流用相量表示，RLC元件用阻抗或导纳表示，画出电路的相量模型，利用KCL，KVL和欧姆定律的相量形式列写出未知电压、电流相量的代数方程加以求解，通过引入相量法，建立了阻抗和导纳的概念，给出了KCL，KVL和欧姆定律的相量形式，由于它们与直流电路的分析中所用的同一公式在形式上完全相同，因此能够把分析直流电路的方法，原理，定律，例如，网孔法，结点法，叠加定理，戴维宁定理，等效电源原理等等直接应用于分析正弦电路的相量模型，其区别仅在于：（1）不直接引用电压电流的瞬时表达式来表征各种关系，而是用对应的向量形式来表征各种关系；（2）相应的运算不是代数运算，而是复数的运算，因而运算比直流复杂。
