| Abstract: | By making use of rotate degress of vector field to determine non-existence of closed orbit about plane, space differential system, we obtain a kind of new determinate method, It is similar to Bendixson, Dulac determinate method. meanwhile, we obtain relative position of closed orbit about plane differential system. |

| Keywords: | rational flow amount rotate degress differential system closed orbit |
