摘　　要：运用Hamilton-Jacobi方程,得到了Kerr-anti-de Sitter黑洞在新tortoise坐标变换下产生非热辐射时粒的频率,并与在广义tortoise坐标变换下的值进行了比较.结果表明,在两种情况下的值是相同的.最后,通过表面引力的方法得到了Kerr-anti-de Sitter黑洞产生热辐射时事件视界处的霍金温度.The frequency of radiation particles is obtained throngh Hamilton-Jacobi function in a new tortoise coordination transformation,when this Kerr-anti-de Sitter black hole radiates non-thermally.What is more,the result is equal to that in the general tortoise coordination transformation.Finally,the Hawking temperature at the event horizon is got by calculating the surface gravity parameter when this Kerr-anti-de Sitter black hole radiates thermally.
