Nonknotty Graph and Its Several Properties

Xu Zhicai(Department of Applied Science and Technology, Beijing University of Posts and Telecommunications, Beijing 100088)  
The concepts of knot,nonknotty graph and knotty graph are given at first. Then, the sufficient-necessary condition for a graph G0 being a nonknotty graph is presented. Some properties of a nonknotty graph are also discussed.
