摘　　要：Rees-表面序列和理想的多重集的联合约化在纤维锥的奇异点的研究中具有重要作用,Rees-表面序列和理想的约化是交换代数的基本研究工具.利用理想和分次模的有限生成性以及映射的同构等方法给出了Rees-表面序列是G(I)-正则序列和联合约化数有限的一些等价刻画.Rees - superficial role in studying the singu deals are fundamental too sequences and joint reduction numbers of the ideal multi - set play relevant arity theory of the fiber cones. Rees - superficial sequences and reduction of is in commutative algebra. In this paper, we give some characterizations of a Rees- superficial sequence G（ I）- regular and joint reduction number, finite- by- finite generated ideals or graded modules and isomorphism map.

关 键 词：Rees-表面序列 联合约化数 分次模 同构
