摘　　要：This paper studies the finite statistical-mechanical entropy of the Schwarzschild anti-de Sitter （ADS） spacetime arising from quantum massless scalar field by using the ＇brick wall＇ approach in the Painlev; and Lemaaitre coordinates. At first glance, it seems that the results would be different from that in the Schwarzschild-like coordinate since both the Painlev; and the Lemaitre spacetimes do not possess the event horizon obviously. However, this paper proves that the entropies in these coordinates are exactly equivalent to that in the Schwarzschild-like coordinate.This paper studies the finite statistical-mechanical entropy of the Schwarzschild anti-de Sitter （ADS） spacetime arising from quantum massless scalar field by using the ＇brick wall＇ approach in the Painlev; and Lemaaitre coordinates.
