英文摘要: We consider a dark energy model with a relation between the equation of state parameter w and the energy density parameter Of derived from thawing scalar field models. Assuming the variation of the fine structure constant is caused by dark energy, we use the observational data of the variation of the fine structure constant to constrain the current value of w(0) and Omega(phi 0) for the dark energy model. At the 1 sigma level, the observational data excluded some areas around w(0) = -1, which explains the positive detection of the variation of the fine structure constant at the 1 sigma level, but Lambda CDM model is consistent with the data at the 2 sigma level.
