摘　　要：两维整体单极黑洞事件视界附近的一个薄层作为Casimir型系统,得到了在Boulware真空、Hartle-Hawking真空和Unruh真空的能动张量.这些值都是在满足Dirichlet边界条件的无质量标量场中得到.应用Wald公理得到了用通常的正规化方法得到的结果.同时,计算了在渐进平直时空下的能量、能量密度和作用在Dirichlet边界上的压强,并由能量得到了Casimir力.A thin layer of the event horizon vicinity under the two-dimension black hole spacetime with a global monopole is considered as a system of the Casimir type.The energy-momentum tensor is derived in Boulware vacuum,Hartle-Hawking vacuum and Unruh vacuum respectively.The values are derived in the massless scalar field which satisfies the Dirichlet boundary conditions.By the Wald s axioms,the result is the same with one by the usual regularized methods.Meanwhile,energy,energy density,and pressure acting on Dir...
