Two distinct perturbative approaches have been recently formulated within General Relativity, arguing for the screening of gravity in the $\Lambda$CDM Universe. In this paper we compare them and show that the offered screening concepts, each characterized by its own interaction range, can peacefully coexist. Accordingly, we advance a united scheme, determining the gravitational potential at all scales, including regions of nonlinear density contrasts, by means of a simple Helmholtz equation with the effective cosmological screening length. In addition, we claim that cosmic structures may not grow at distances above this Yukawa range and confront its current value with dimensions of the largest known objects in the Universe.

最近在广义相对论中提出了两种截然不同的摄动方法，主张对重力场中的重力进行筛选。 $\Lambda$CDM宇宙。在本文中，我们将它们进行了比较，并显示了所提供的筛选概念（每个都具有自己的交互范围）可以和平共处。因此，我们提出了一个联合方案，通过具有有效宇宙学筛选长度的简单亥姆霍兹方程，确定了包括非线性密度对比区域在内的所有尺度上的重力势。此外，我们声称宇宙结构可能不会在此Yukawa范围以上的距离处生长，并以宇宙中最大的已知物体的尺寸面对其当前值。
