用一种新的Tortoise坐标变换研究动态Kerr黑洞视界表面引力及量子非热辐射特征

Research on the Horizon Surface Gravity and the QuatumNonthermal Radiation of Nonstationary Kerr Black Holeby Using a New Tortoise Coordinate Transformation

用一种新的tortoise坐标变换研究了动态Kerr黑洞时空中的Hamilton Jacobi方程,其结果表明,根据Hamilton Jacobi方程可以研究黑洞的量子非热辐射特征,也可以研究黑洞视界表面引力.

Hamilton-Jacobi equation in the spacetime of nonstationary Kerr black hole is studied by using a new tortoise coordinate transformation.It shows that the Hamilton-Jacobi equation can discuss not only the nonthermal radiation,but also the surface gravity of the black hole.
