这个波形可以被看作是下列原理的叠加(图22和平台5)。全部这些波形的叠加整合结果变成图21所示的典型漏极电流。
This waveform can be presented as a superposition of the following elements (Fig. 22 and Tab. 5). The superposition of all these elements results in a typical drain current shown in Fig. 21.
主要用途是将叠加在直流电流上的交流分量限定在某一规定值。
The main purpose is to direct current superimposed on the exchange of a specified weight limit value.
采用基于叠加原理的短路电流计算方法，克服了传统的对称分量法应用于配电网短路电流计算时所遇到的困难。
Furthermore, the superposition theorem is then adopted in the approach, which overcomes the difficulties when applying the symmetrical components to the short circuit calculation.
