孤立系统的质心概念以前已经编码在所谓的好截面的定义中。本文推广了线性化方程在良截面上解的存在性证明，并给出了放宽辐射条件的良截面的局部存在性证明。我们报告这个家庭的解决方案的可微性和非自交叉性能。我们还证明了整体存在的nice部分。
The notion of center of mass for an isolated system has been previously encoded in the definition of the so-called nice sections. In this article we present a generalization of the proof of existence of solutions to the linearized equation for nice sections, and formalize a local existence proof of nice sections relaxing the radiation condition. We report on the differentiable and non-self-crossing properties of this family of solutions. We also give a proof of the global existence of nice sections.
