利用静态球对称黑洞Dirac场的统计熵,导出广义球对称带电静态黑洞的广义Stefan—Boltzmann定律,得出了黑洞的辐出度与视界温度的4次方成正比的结论。利用热质点模型,研究了广义球对称带电静态黑洞的辐射能通量和辐射功率,指出当截断的固有厚度η黑洞质量m、黑洞电荷Q及ψ取定后,距离黑洞遥远的观测者所接收到的辐射能通量与观测者到黑洞距离的平方成反比。
By using the statistical entropy of the Dirac field of the static spherically symmetric black holes, the generalized Stefan-Boltzmann' s law of the general static spherically symmetric charged black holes was obtained. The result showed that the radiant emittance of a black hole was proportional to the quartic power of the temperature of its event horizon. The radiation energy flux and radiation power of the general static spherically symmetric charged black hole were studied by using the thermal particle model. It was found that when the values ofη, m, Q and ψwere fixed, the radiation energy flux received by the observer was inversely proportional to the square of the distance between the observer and the black hole.
