摘　　要：根据黑洞表面引力定义、Klein-Gordon方程和Hamilton-Jacobi方程，分别计算了Brans-Dicke参数在-5／z≤ω〈-3／2时所描述的稳态轴对称Brans-Dicke-Kerr-Newman黑洞的表面引力．计算结果表明，3种方法都能得到一致的结果．但与表面引力相联系的黑洞视界温度却为零，违反了宇宙监督原理．这类黑洞很可能是天体演化过程中的理想模型．The surface gravitation of the stationary and axisymmetric Brans-Dicke-Kerr-Newman black hole with the Brans-Dicke parameter values --5/2≤ω〈-3/2 is respectively calculated according to the definition of surface gravitation of black hole, Klein-Gordon equation and Hamilton-Jacobi equation. The result shows that the expression of surface gravitation for the three methods is the same and the corresponding horizon temperature of the black hole is zero. This is an offence against cosmic censorship, and this kind of black hole is very likely an ideal model in evolvement of celestial bodies.
