论文摘要
在本文中，已经探索了一般球形对称空间的量规选择。我们分别为Detweiler Easy Gauge和Regge-Wheeler仪表构造规格不变变量和主方程。还研究了$ L = 0,1 $的特定案例。我们的结果提供了一般球形对称时间的度量扰动的分析计算，可以应用于各种情况，包括有效的一体问题。提出了一个简单的示例，以说明公制扰动组件与源扰动项如何相关。
In this paper, the gauge choices in general spherically symmetric spacetimes have been explored. We construct the gauge invariant variables and the master equations for both the Detweiler easy gauge and the Regge-Wheeler gauge, respectively. The particular cases for $l=0,1$ are also been investigated. Our results provide analytical calculations of metric perturbation in general spherically symmetric spacetimes, which can be applied to various cases, including the Effective-One-Body problem. A simple example is presented to show how the metric perturbation components are related to the source perturbation terms.
