采用一种新的Tortoise坐标变换，约化视界附近Klein-Gordon方程，得到了黑洞的Hawking温度；并用薄膜模型计算了黑洞熵，得到了熵与视界面积成正比的Bekenstein关系.用这种Tortoise坐标变换，还可以使计算动态黑洞熵时所用的截断因子变得与静态和稳态情况相同.

Considering the Klein_Gordon equation near the event horizon, Hawking temperature is calculated under a new Tortoise coordinate transformation. In the meantime , the cut-off parameter in thin membrane model is also simplified to the same as that in the static and stationary cases.-
