摘　　要：窖泥氧化还原电位(Eh值)决定着窖泥中铁存在形态。当窖泥处于中度还原状态时(Eh:0～200mv),活性铁含量最高,也最易出现老化现象;当窖泥处于强度还原状态时﹙Eh<0mv﹚,Fe2+转变为沉淀铁(FeS)老窖形成。通过人为控制条件,可促进窖泥微生物活动,加速新窖还原化进程,从而促成"百年老窖"形成。The redox potential （Eh value） determines the iron form in the cellar mud. When the redox potential Eh is between 0-200 mv, the content of the active iron is highest, and the aging phenomenon is most liable. When the redox potential Eh is lower than 0 mv, Fe^2＋ changes into FeS, and aged cellar mud is formed. By the artificial control, the microbial activity and the redox process can be accelerated, therefore the ＂the hundred year cellar＂ will be formed.
