在曲率三阶单圈近似下，计算了引力理论拉格朗日量的真空修正。在零无穷远附近的时空域中，场论的环展开给出了正确的结果。有效作用量中形状因子的小行为决定了引力坍缩产生的真空辐射。这些行为如下所示，它们包含明显违反渐近平坦性的意外项。这些项最终应相互抵消，以给出真空能量的有限通量。
The vacuum corrections to the Lagrangian of gravity theory are calculated in the one-loop approximation to third order in the curvature. In the spacetime domain near null infinity the loop expansion of field theory gives the correct results. The small- behaviours of the form factors in the effective action determine the vacuum radiation by the gravitational collapse. These behaviours are presented below and they contain unexpected terms which apparently violate the asymptotic flatness. These terms should ultimately cancel to give the finite flux of vacuum energy.
