 摘要： 通过似正规模，采用两种量子化方法计算了多维极端ReissnerNordstrm黑洞的熵量子谱。结果表明，从两种量子化方法所得的熵谱是一致的，此黑洞的熵量子谱与黑洞的参量及微扰场的参量无关，但与时空的维度有关。对于确定的维度，熵量子谱是等间距的。

 Abstract: The quantum entropy spectrum of ddimensional extreme ReissnerNordstrm black holes is calculated with two quantization methods respectively, where the quasinormal modes of the black holes are employed. Results show that the quantum entropy spectra obtained from the two quantization methods are consistent. The entropy spectrum is irrelevant to the parameters of the black hole and the perturbation field, but relevant to the spacetime dimension. For a fixed dimension, the spectrum is equidistant.

 Key words: extreme RN black hole; black hole entropy; quantization; quasinormal modes
