摘要：
We study the thermodynamical and geometrical behaviour of the black holes that arise as solutions of the heterotic string action. We discuss the near-horizon scaling behaviour of the solutions that are described by two-dimensional Anti-de Sitter space (AdS(2)). We find that finite-energy excitations of AdS(2) are suppressed only for scaling limits characterized by a dilaton constant near the horizon, whereas this suppression does not occur when the dilaton is nan-constant.
