摘要：
A solution of codimension 2 brane is found for which four-dimensional Friedmann cosmology is recovered on the brane with time-dependent tension, in the Einstein frame. The effective parameter p/p of equation of state on the brane can be quintessence like, de Sitter like or phantom like, depending on the integration constants of the solution.
