One problem of the $\Lambda$CDM model is the tension between the $S_8$ found in Cosmic Microwave Background (CMB) experiments and the smaller one obtained from large-scale observations in the late Universe. The ${\sigma }_8$ quantifies the relatively high level of clustering. Likelihood analyses of the Redshift Space Distortion (RSD) selected data set yields: $S_8=0.700_{-0.037}^{+0.038}$. The fit has $3\sigma$ tension with the Planck 2018 results. With Gaussian processes method a model-independent reconstructions of the growth history of matter in-homogeneity is studied. The fit yields $S_8=0.707_{-0.085}^{+0.085},0.701_{-0.089}^{+0.089}$, and $0.731_{-0.062}^{+0.063}$ for different kernels. The tension reduces and being smaller then $1.5\sigma$. With future measurements the tension may be reduced, but the possibility the tension is real is a plausible situation.

一个问题 $\Lambda$CDM模式是两者之间的张力 ${\mathrm{小号}}_8$在宇宙微波背景（CMB）实验中发现，而较小的则是从宇宙后期的大规模观测中获得的。的${\sigma }_8$量化相对较高的聚类水平。对Redshift空间失真（RSD）所选数据集的可能性分析得出：${\mathrm{小号}}_8=0。700_{-0。037}^{+0。038}$。适合有$3\sigma$普朗克2018年业绩紧张。使用高斯过程方法，研究了物质非均质性生长历史的模型独立重构。合适的产量${\mathrm{小号}}_8=0。707_{-0。085}^{+0。085}，0。70{\mathrm{1个}}_{-0。089}^{+0。089}$和 $0。73{\mathrm{1个}}_{-0。062}^{+0。063}$对于不同的内核。张力减小然后减小$\mathrm{1个}。5\sigma$。随着将来的测量，张力可能会减小，但是张力真实存在的可能性是合理的。
