In this talk, I will first recall some background about the Gromov-Hausdorff convergence theory, and then state the bubble tree convergence results of noncollapsing degenerating Einstein 4-manifolds obtained by the works of many authors. At last, I will introduce some results about the expansion of Ricci flat ALE metrics in harmonic coordinates at the infinity.
