论文摘要
我们研究了在共形性重力下从非旋转奇异性黑洞的鹰辐射的稀疏性。我们对无质量标量场的灰体因子进行了严格的结合，并计算出黑洞的鹰辐射的稀疏性。此外，我们研究了灰体因子的依赖性以及鹰辐射对共形参数的稀疏性。我们的研究表明，来自黑洞的鹰辐射极为稀疏。当保形参数很大时，保形参数的增加将导致更稀疏的鹰辐射，而如果保形参数很小，则较小的鹰辐射。
We study the sparsity of Hawking radiation from nonrotating singularity-free black holes in conformal gravity. We give a rigorous bound on the greybody factor for massless scalar field and calculate the sparsity of Hawking radiation from the black hole. Besides, we investigate the dependence of the greybody factor and the sparsity of Hawking radiation on the conformal parameters. Our study shows that the Hawking radiation from the black hole is extremely sparse. When the conformal parameters are large, the increase of conformal parameters will lead to an even more sparse Hawking radiation, while to a less sparse Hawking radiation if the conformal parameters are small.
