Abstract: As we known,N.Sato defined semi-boundary links of two compon- ents in 1984,and gave the construction of special Seifert pairs.In this paper,we defined first semi-boundary and strong semi-boundary links of any number components,and prove the invariance of semi-boundary link cobordism,For one dimensional 、spherical semi-boundary links,a simple method of constructing Seifert surfaces is given,by which we obtain the equivalence of semi-boundary and strong semi-boundary links.We apply finally this similar method to boundary links.
