直流分量 [zhí liú fèn liàng]
DC component
direct-current component
direct-current component
- 非正弦周期函数的有效值等于直流分量与各次谐波分量有效值的平方和的平方根。
3 The effective value of a non sinusoidal periodic function is equal to the square root of the square sum of the constant component value and every harmonic component effective value. - 三电平同步方式消除了直流分量，提供了更有效的办法来确定同步信号在信号链的位置。
Tri-level sync eliminatesthe DC component and provides a more robust way to identify the comingof synchronization in the signal chain. - 摘要能否滤除非系统频率整数倍的谐波和衰减的直流分量是衡量保护算法抗干扰能力的重要特徵。
A protection algorithm can be judged as having strong capability of anti interference if it can eliminate decaying direct current component and high harmonic whose frequency is not the integer times of system base-frequency.
