Solar system has experienced planetary migration in its formation stage. Especially, Neptune has an evidence of outward migration in the 3:2 mean motion resonance in the Kuiper belt objects. In the point of view of planetary formation theory, outer ice giant planet needs planetarymigration to shortening its growth time. Several simulations about planetary migration has done, and some results indicate that planet can migrate outward when disk has enough mass, but there are few works to understand the basic mechanism. In our work, we would like to focusattention on the mass flux that step over the planet to formulate the planetary migration. That kind of mass flux works as a fuel of migration.
