反馈fǎnkuì
1.把放大器的输出电路中的一部分能量送回输入电路中,以增强或减弱输入讯号的效应。增强输入讯号效应的叫正反馈;减弱输入讯号效应的叫负反馈。正反馈常用来产生振荡;负反馈能稳定放大,减少失真,因而广泛应用于放大器中。{feedback; process of returning part of the energy of the output circuit of an amplifier to the input circuit to boost the effects of input signals (positive feedback) or to weaken them (negative feedback). Positive feedback is oft. used to produce vibration, while negative feedback has been widely applied in amplifiers for its property of stabilizing amplification and reducing distortion.}
2.医学上指某些生理的或病理的效应反过来影响引起这种效应的原因。起增强作用的叫正反馈;起减弱作用的叫负反馈。{feedback; physiological or pathological effects that conversely affect their causes, either boosting the effects (positive feedback) or weakening them (negative feedback)}
3.(信息、反映等)返回{feedback (of information, reactions, etc.)}:
市场销售情况的信息不断～到工厂。{The factory constantly received feedbacks on market sales.} |
