最好别直接用有道金山之类翻译软件来翻译,要是能我就不上这来了.
Many different types of network elements exhibit different behavior to the different symmetrical components.For example,as we will see shortly,transmission lines have one impedance for positive and negative sequence,but an entirely different impedance to zero sequence.Rotating machines have different impedances to all three sequences.
To illustrate the independence of symmetrical components in balanced networks,consider the transmission line illustrated back in Figure 20 of Installment 3 of these notes.The expressions for voltage drop in the lines may be written as a single vector expression:

不同的网络元件对不同的对称零部件会呈现不同的反应.比如我们立刻能看到的,输电线路对正序和负逆序都有相同的电阻抗,但对零序部分则会有一个截然不同的电阻抗.旋转电机对这三种序列都有着不同的电阻抗.【注:与楼上不同~是旋转电机对正负零3种序列的电阻抗都是 不 同 的!】
为了显示平衡网络中的对称零部件的独立性,请参看上文的[装置3-图形20]中的传输线及其注释.传输线的电压骤降可以表示为这一个矢量式:【此处应该有个表达式】
