摘　　要：利用Rob inson和W iczek提出的方法,我们从反常的角度研究了带电的d ilaton-axion黑洞的霍金辐射,为了得到规范不变量和广义规范不变量,引入了规范流和能动张量流,最后通过去除反常得到了在事件视界处的霍金温度,所得的结果与来自于普朗克分布的辐射谱的结果相一致.Following the method proposed by Robinson and Wiczek,Hawking radiation of charged dilaton-axion black hole is investigated from the anomalous point of view.In this paper,the gauge current flux and the energy momentum tensor flux are introduced in order to hold the gauge invariant and general coordinate covariant at quantum level.Finally,after canceling the anomaly,we can get the Hawking temperature at the event horizon which is consistent with that from Hawking radiation spectrum with Plank distribution.
