把洛仑兹破缺的标量场方程推广到弯曲时空中, 并通过Aether-like项对标量场方程进行修正, 该项所产生的效应也会影响到黑洞时空视界附近处的物理效应. 接着, 进一步在半经典近似下得到了修正的Hamilton-Jacobi方程, 然后用这一修正的Hamilton-Jacobi方程研究了史瓦西黑洞的隧穿辐射特征, 并讨论了洛仑兹破缺对黑洞霍金辐射和黑洞熵的影响. 结果表明,
${{ u}^\alpha } = {\text{δ}}_t^\alpha {u^t}, {\text{δ}}_r^\alpha {u^r}$ 形式的Aether-like项的效应可能使黑洞温度增加, 而黑洞熵降低. 该工作可以帮助我们更深刻地理解弯曲时空中的洛仑兹破缺效应的物理性质.-

In this paper, the Lorentz-violating scalar field equation is generalized in curved spacetime, and we find that the aether-like terms modify the scalar field equation, so that the effect can correct the properties near the event horizon of black hole spacetime. We then obtain the modified Hamilton-Jacobi equation by semi-classical approximation, and investigate the Hawking radiation and black hole thermodynamics in Schwarzschild black hole spacetime. The results show that the effects of aether-like terms increase the temperature of black hole, but reduce the entropy of black hole as${{ u}^\alpha } = {\text{δ}}_t^\alpha {u^t}, {\text{δ}}_r^\alpha {u^r}$ . This work can help to understand the properties of Lorentz-violating in curved spacetime.-
