摘　　要：采用乌龟坐标变换,在视界面附近化简Klein-Gordon场方程,得到在视界面附近的辐射温度.用薄膜brick-wall模型,选择适当的截断因子和薄膜厚度,得到在视界面附近薄膜上的熵,结果表明黑洞熵与视界面积成正比.By adopting tortoise coordinate transformation and changing the Klein-Gordon field equation to be wave equation near the vision interface, the radiation temperature of the black hole can be gotten. Counting the black hole＇s entropy with film brick-wall model indicates the entropy is in direct proportion to the vision interface area and the expression form is as simple as the static or steady state is.
