摘要：

For the two-charge extremal holes in string theory we show that the Bekenstein entropy obtained from the area of the stretched horizon has a statistical interpretation as a "coarse graining entropy": different microstates give geometries that differ near r=0 , and the stretched horizon cuts off the metric at r=b where these geometries start to differ.
