摘　　要：利用Wentzel-Kramers-Brillouin近似计算了Taub-NUT时空事件视界附近自旋为1/2,1,3/2,2等无质量场的熵密度、压强和能量密度.结果表明,自旋场附近的热力学量不仅具有与平直时空相同的主导项,还多了两项自旋依赖的附加项.The entropy density, energy density and pressure of the spin fields near the event horizon in Taub-NUT spacetime are investigated by using the Wentzel-Kramers-Brillouin approximation. It is shown that any one of the thermodynamic quantities has three terms. The first term has the same form as that in flat spacetime, the second and the third terms are spin-dependent terms due to the spin fields.
