灰度失真、噪声、几何失真等误差因数会影响匹配性能，本文给出了相对应的处理方法。

The error factors such as intensity distortion, noise and geometry distortion will affect matching performance, so the paper gives the opposite processing methods.

内部的功率因数校正（PFC）电路以临界导通模式（CCM）工作，可获得高功率因数、低总谐波失真（THD）及直流电压调整。

PFC circuitry operates in critical conduction mode(CCM)and provides for high PF, low THD and DC bus regulation.
