摘　　要：利用协变反常取消法研究一种类RN黑洞的霍金辐射.结果表明,为了在量子水平上保持有效场的广义协变性和规范不变性,类RN黑洞的出射波的电荷总通量和能量总通量必须与一个具有相应化学势和霍金温度的(1+1)维黑体辐射的总通量相等.该结论支持了Robinson等人的观点,同时又使其在静态条件下得到了扩展.Using the method of anomaly cancellation to a RN-like black hole, it shows that in order to hold general covariance and gauge invariance at quantum level the total flux of charge and energy-momentum in each outgoing partial wave of a charged quantum field in this black hole must be equal to that of a （1 ＋ 1）-dimensional blackbody at Hawking temperature with the appropriate potential, which supports Robinson and Wilczek＇ s opinion.
