论文摘要
在微米 - 弧度和纳米弧度准确度尺度上，在太阳系中的光轨迹的精确建模需要在后线性后近似的太阳系体的度量张量。多极后科斯基的形式主义代表了一个框架，用于确定紧凑型物质源外部的度量密度，这可以被视为巨大的太阳系主体。通常称为哥特式公制的度量密度的知识允许推断公制张量。考虑了如何确定重力场方程的度量密度和度量张量的一些方面。
A precise modeling of light trajectories in the solar system on the sub-micro-arcsecond and nano-arcsecond scale of accuracy requires the metric tensor of solar system bodies in post-linear approximation. The Multipolar Post-Minkowskian formalism represents a framework for determining the metric density in the exterior of a compact source of matter, which can be regarded as massive solar system body. The knowledge of the metric density, frequently been called gothic metric, allows to deduce the metric tensor. Some aspects are considered about how to determine the metric density and the metric tensor from the field equations of gravity.
