摘　　要：In this paper,it is proved that, let M be a tubular module, then there is a tubular module N,such that End(MN) is a quasi-hereditary algebra. And in the case of M bing a indeconposable tubular module, this paper characterizes the below bound of the number of indecomposable direct summands of N.In this paper,it is proved that, let M be a tubular module, then there is a tubular module N,such that End(MN) is a quasi-hereditary algebra.
