| Abstract: | This paper shows that if only there is straight line on the uniparted hyperboloid,then it must be rectilinear generator of u-family or v-family as well known,then the uniqueness about u and v-family rectilinear generator of uniparted hyperboloid is solved,and discussion about it in other papers are simplified. |
