研究了被挤压的卡鲁扎-克莱因黑洞周围薄圆盘中的吸积过程，并探讨了额外维度尺度ρ0对圆盘物理性质的影响。结果表明，随着参数ρ0的增加，薄吸积盘的能流、转换效率、辐射温度、光谱光度和光谱截止频率减小，而盘的内边增大。这意味着额外的维度尺度在盘中的质量吸积过程中留下印记。
We study the accretion process in the thin disk around a squashed Kaluza–Klein black hole and probe the effects of the extra dimensional scale ρ0on the physical properties of the disk. Our results show that with the increase of the parameter ρ0, the energy flux, the conversion efficiency, the radiation temperature, the spectra luminosity and the spectra cut-off frequency of the thin accretion disk decrease, but the inner border of the disk increases. This implies that the extra dimension scale imprints in the mass accretion process in the disk.
