实践证明﹐三相全波整流和稳压直流相当﹐对镀层组织几乎没有什么影响﹐而其它波形则影响较大。
Practice proves, the wave rectifier and three-phase regulated dc quite, the coating structure little impact, and other waveform is big effect.
经过整流后得到的是一个频率为交流电源两倍的单极波形。
This produces a waveform of one polarity operating at a frequency twice that of the mains supply.
从分析常用的简单可控整流电路和波形存在一定问题入手，提出改进的必要性。
The issues of commonly used simple controllable rectification circuit and waveform were analyzed, and the improvement necessity was put forward.
