For integersaandbsuch that 0 ⩽a⩽b, a graphGis called an [a,b]-graph ifa⩽dG(x) ⩽bfor every vertexxofGand a factorFof a graph is called an [a,b]-factor ifa⩽dF(x) ⩽bfor every vertexxofF. We prove the following theorems. Let 0 ⩽l⩽k⩽r, 0 ⩽s, 0 ⩽uand 1 ⩽t. The an [r,r+s]-graph has a [k,k+t]-factor ifks⩽rt. Moreover, if (k−l)s+ (r−k)u⩽ (r−l)t, then an [r,r+s]-graph has a [k,k+t]-factor which contains a given [l,l+u]-factor.
