  We propose the relationships between the noncommutative solitons and the
(fractional) D-branes on the C^2/Z_n orbifold and extend the solution
generating technique for the orbifold. As applications, we determine how
tachyon condensations occur in various D-Dbar systems on the orbifolds. The
calculations give results consistent with BSFT. The extended solution
generating technique enables us to calculate more general decay modes of D-Dbar
systems.
