摘要	In the studies on pre-recombination early dark energy (EDE), the evolution of Universe after recombination is usually regarded as Lambda CDM-like, which corresponds that the equation of state of dark energy responsible for current accelerated expansion is w =-1. However, in realistic models, wmight be evolving. We consider the parametrizations of wwith respect to the redshift z in Axion-like EDE and AdSEDE models, respectively. We performed the Monte Carlo Markov chain analysis with recent cosmological data, and found that the bestfit w(z) is compatible with w(0) = -1, wa = 0(the cosmological constant) and the evolution of wis only marginally favored, which so has little effect on lifting the bestfit value of H-0.
