继电保护原理与应用(第三版)3.1-3.5(4)

where c is the phasor; c* is its conjugate; x is the real value (alternate: Re c or c’ ); y is the imaginary value (alternate: Im c or c”); jcj is the modulus (magnitude or absolute value); and f is the phase angle (argument or amplitude) (alternate: arg c).
式中，c是相量；c*是其共轭；x是实值（备选值：Re c或c’）；y是虚值（备选值：Im c或c”）；jcj是模数（幅度或绝对值）；f是相角（参数或幅度）（备选值：arg c）。
The modulus (magnitude or absolute value) of the phasor is相量的模数（幅值或绝对值）为

From Equation 3.1 and Equation 3.3, 从方程式3.1和方程式3.3中，
