| 摘 要： | 以平坦的闵可夫斯基时空为背景，利用量子微扰的方法，对四导数引力中两点间曲率真空相关函数关于引力场的最低阶贡献进行计算。结果表明，在四导数引力时空两点间的曲率真空相关函数首项不为零，可能存在曲率激发。

| Abstract: | Under the fiat Minkowski space-time background, we give a lowest-order calculation perturbatively of two-point curvature vacuum correlation functions in four-derivative gravity, resulting in that the leading terms of curvature vacuum correlation functions are not zero and the possibility of curvature excitation exists. |

| Keywords: | perturbation curvature excitation quantum gravity |
