报告摘要：The luminosity distance,DL, and the angular diameter distance, DA, are both fundamental observations in astronomy.They satisfy an important relationship known as the distance–duality (DD) relation, DL/DA=(1+z)^2. In this talk, I will introduce how to perform a cosmological-model-independent test for this relation, and the meanings of testing the distance-duality relation.
