负反馈的最重要作用在于使放大器总增益不至于因基本放大器增益的改变而变化，其总增益的大小完全取决于反馈网络的元件参数。
The most important effect of this is to make the overall amplifier gain almost immune to changes in the amplifier unit gain, and dependent almost entirely on the feedback network components.
在网络分析中，当元件参数发生变化时，我们用绝对灵敏度来研究它们对网络响应的影响。
In network analysis, to consider the effect on circuit response of variation in component parameters, the absolute sensitivity is applied.
采用常规的电力系统元件模型和参数进行数值仿真所得的频率变化曲线与实测曲线偏差较大。
As for the numerical simulation by traditional power system component models and parameters, the obtained dynamic frequency curves evidently diverge from measured ones.
