求翻译：一般可将运放简单地视为：具有一个信号输出端口和同相、反相两个高阻抗输入端的高增益直接耦合电压放大单元，因此可采用运放制作同相、反相及差分放大器。是什么意思？

Generally regarded as the op amp simply: with a signal output port and the same phase, reversed-phase high-impedance inputs of two high-gain direct-coupled voltage amplifier unit, so the op amp can be used to produce the same phase, inverting and differential amplifiers.

operational amplifiers in general can be seen simply as a signal output ports, and with each other, and anti-sang two high-impedance input port of high gain direct-coupled voltage amplifier module production, and therefore can be used with operational amplifiers, anti-sang and differential amplifier

Transports puts like the chart to have two input end a (opposition input end), b (synchronism input end) and out-port o.Also is called separately the reverse input end non-reverse input end and the out-port.When voltage U- adds in a end and the public end (the public end is the voltage for the zero

General operational amplifiers can be simply considered as having a signal output port and both phase and reversed-phase high-impedance input directly coupled to the high-gain voltage amplifier unit, and therefore can be produced using operational amplifiers with phase and reversed-phase and the dif
