英文摘要	In this paper, the effects of dark radiation (DR) are tested. Theoretically, the phase-space analysis method is applied to check whether the model is consist with the history of our universe which shows positive results. Observationally, by using the observational data (SuperNovae Legacy Survey (SNLS), Wilkinson Microwave Anisotropy Probe 9 Years Result (WMAP9), Planck First Data Release (PLANCK), baryon acoustic oscillations (BAO), Hubble parameter data (H(z)) and Big Bang nucleosynthesis (BBN)), the DR is found to have the effect of wiping out the tension between the SNLS data and the other data in a flat Lambda CDM model. The effects of DR also make the best fit value of N-eff slightly larger than 3.04.
