研究球对称荷电蒸发黑洞非热辐射的新方法

A NEW METHOD FOR THE STUDY ON THE NON-THERMAL RADIATION FROM THE EVAPORATING CHARGE BLACK HOLES OF SPHERICAL SYMMETRY

从Ｒｅｉｓｓｎｅｒ－Ｎｏｒｄｓｔｒｏｍ度规出度，直接用时间ｔ表述黑洞的动态特征，计算出了球对称荷电蒸发黑洞非热辐射的频率范围，其范围不仅与随时间变化的黑洞质量Ｍ（ｔ）和黑洞电荷Ｑ（ｔ）有关，而且还与黑洞的蒸发率有关．

The non-stationary characteristic is represented directly by t from the Reissner-Nordstom metric. The frequency range of the non-thermal radiation from evaporating charge black holes of spherical sym-metry is caculated.The range depends on not only the M(t),i.e. ,the mass varying with t,and onthe Q(t),i.e. , the charge varying with t,but also on the evaporating rate.
