衰减周期 meaning in Chinese

damping period
decay period
fading period

Compared with the traditional curve - based method , this method can calculate the currents with high accuracy and little user effort . it can automatically calculate the periodic components of varying short circuit currents at anytime , and the aperiodic components of the symmetric short circuit currents
该计算机算法大大减轻了传统运算曲线算法的工作量，且具有较高的准确度，能够自动完成系统短路时任意时刻电流衰减周期分量的求解，及对称短路时短路电流非周期分量的求解。
