摘　　要：应用泛函积分方法推导了量子Thirring模型中的传播子和有效势,计算了二维点物质黑洞和dilaton黑洞模型中费米物质的能量密度涨落,在相同的物理条件下,发现dilaton黑洞外费米物质的能量密度涨较大.In this paper,the propagator and the effective potential in quantum Thirring model are derived by using the functional integral method,and the energy density fluctuations for coupled Fermi matter are calculated in two-dimensional point matter black hole and dilaton black hole models separately.We find that energy density fluctuation outside dilaton black hole is stronger under the same physical conditions.

关 键 词：泛函积分 Thirring模型 黑洞 能量密度涨落
