摘　　要：利用改进的brick-wall模型推导出自旋为2的引力场对动态Vaidya-Bonner黑洞熵的贡献,在自然单位制中其值为A/2;这表明,当选择与标量场相同的截断因子时,其熵为标量场的2倍,为Dirac场的4/7.The contribution of gravitational field of spin 2 to the entropy of Vaidya-Bonner black hole is calculated by using thin film brick-wall model proposed by Zhao Zheng et al., which is found to be A/2 in nature unit system. It is shown to be just two times the scalar field and 4/7 times the Dirac field when the truncation factor is the same as scalar fields.
