Quantum entropy of the non-static black hole in (2 + 1)dimensions
(2+1)维动态黑洞的量子熵

In the tortoise coordinates,the quantum entropy of the non static black hole in (2 1)dimensions due to scalar fields has been investigated by using the brick wall model.It is shown that the entropy of scalar fields within the thin region near the horizon has the same structure as that of the black ho1e.In particular,the quantum entropy satisfies the perimeter law of the entropy for the static case.
