In PCB design, if all units grounded in one point, the self-oscillation by circuit feedback along the earth wire or the power supply wire can be avoided. 在PCB布线时采用一点接地方法,避免后级电路通过电源和地线反馈至前级电路引起自激。
The electrical coil, the paintings were grounded in their circuit and the circuit voltage, the TAC, the DC Circuit started painting into several independent parts. 将电气的线圈、接地分别画在所属的电路中,并将整个电路的电压等级、交、直流回路展开,画成几个独立的部分。
