【Abstract】 This paper discussed the properties of function classes defined by an integral operator intioduced by Sagalean (4), obtained more generalized results than those of Sagalean(5) and Bajpai (2), gave an example to show that this operator does not preserve spirallike properties, and finally investigated its "inverse problem"更多还原
