%X 摘要： 给出了所有弱挠自由Rees商序S-系具有某种平坦性质的序幺半群刻画,解决了弱挠自由Rees商序S-系的同调分类问题。作为应用,给出了挠自由以及序挠自由Rees商系的同调分类。<br>Abstract: The characterization of pomonoids over which all weakly torsion free Rees factor S-posets have some kind of flatness is given, and the homological classification problem of weakly torsion free Rees factor S-posets are obtained. As applications, the homological classification of torsion free and po-torsion free Rees factor S-posets are got
