主　　题：Map enufunction Euler trail Lagrangian inversion near-4-regular Eulerian m ap(trail). 

摘      要：In this article the rooted planar near-4-regular Eulerian trails are enum erated and an explicit form ula for such m aps is presented. Further, the rooted near-4-regular Eulerian m aps on the torus are counted in an exact w ay.
