因此它可以把“两倍于电源频率的直流电”进行“平滑化处理”，成为一个接近恒定的直流电。
Therefore it can be seen that it will "smooth" the "twice mains frequency DC" into a near constant DC voltage.
带隙基准电压源之所以是模拟电路中重要的模块，是因为它能够提供近似恒定的参考电压，这个电压不随温度，电源电压，工艺的变化而变化。
Bandgap reference voltages are important analog circuit blocks. It can provide a nearly constant reference voltage which is stabilized over process, power supply and temperature variation.
