In this paper the authors start with the notion of a standard base of an ideal in a local ring (in definition 1.6, \(f^*_ 1,...,f^*_ r\) should be a minimal set of generators of \(J^*)\) and investigate various properties of a standard base, particularly in relation to the elements (resp. their initial forms) forming a regular sequence, and the Koszul complex corresponding to the initial forms. The paper concludes with some application and examples.
