在Tortoise坐标系中，利用brick-wall模型研究了来源于标量场的(2+1)维动态黑洞的量子熵.结果表明，在视界附近的薄区域内标量场的熵与黑洞熵有相同结构.特别是在静态情况下，量子熵满足熵的周长律.

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.-
