摘要：
We apply the entropy function formalism to non-extremal D1D5 and D2D6NS5-branes who set throat approximation is given by the Schwarzs child blackhole in AdS(3) x S-3 x T-4 and AdS(3) x S-2 x S-1 x T-4,respectively.We find the Bekenstein-Hawking entropy and the (a') R-3(4) corrections from the value of the entropy function at its saddle point.While the higher derivative terms have no erect on the temperature,they decrease the value of the entropy.
