外文摘要：We extract key information on dark energy from current observations of BAO,OHD and H0,and find hints of dynamical behavior of dark energy.In particular,a dynamical dark energy model whose equation of state crosses-1 is favored by observations.We also find that the Universe has started accelerating at a lower redshift than expected.
