讨论了费米子在五维双荷黑环中的隧穿特征.通过拖曳坐标变换将五维降为四维,在拖曳坐标系中对费米子隧穿辐射进行研究.结果表明,四维时空中同样可以得到五维黑环的霍金温度.
The tunneling characters of fermions in dyonic black rings are investigated in this paper. We perform the drag ging coordinate transformation on the metric to reduce five dimensions to four dimensions, and then investigate the fermions tunneling radiation in the dragging coordinate system. The result shows that the temperature can be also gotten in the 4- dimensional spacetimes.
