摘要
Hubble tension between the local measurement and global observation has been a key problem in cosmology. In this paper, we consider the quintessence scalar field, phantom field and quintom field as the dark energy to reconcile this problem. Different from most previous work, we start from the dimensionless equation of state (w) of dark energy, not a parameterization of potential. The combined analysis shows that observational data sets favor Hubble constant H0=71.3(-0.917)(+0.854)kms(-1)Mpc(-1) b h (2) and smaller omega( c ) h (2) than the standard lambda CDM model. We finally analyze a possible reason of Hubble tension from the kinematic acceleration a'' a'' z > 0.5. However, they increase and deviate from each other at low redshift, especially in the near future. Only the a''
