We investigate the observational viability of a class of α-attractors inflationary models in light of the most recent Cosmic Microwave Background (CMB) and Large-Scale Structure (LSS) data. By considering a double-well potential we perform a slow-roll analysis to study the behavior of this class of models, which is a continuous interpolation between the chaotic inflation for large values of α and the universal attractor, i.e., $n_s=1-2/N$ and $r=\alpha 12/N^2$ for small α, where $n_s$ is the scalar spectral index, r is the tensor-to-scalar ratio, and N is the e-fold number. In order to explore the parameter space of the model, we also perform a MCMC analysis and find $\alpha =7.56\pm 5.15$ (1σ).

根据最新的宇宙微波背景（CMB）和大规模结构（LSS）数据，我们研究了一类α吸引子膨胀模型的观测可行性。通过考虑双井势，我们进行了慢速滚动分析，以研究此类模型的行为，这是在较大的α值的混沌膨胀与通用吸引子之间的连续插值，即${ñ}_s=\mathrm{1个}-\mathrm{2个}/ñ$ 和 $\mathrm{[R}=\alpha 12/{ñ}^{\mathrm{2个}}$对于小α，${ñ}_s$是标量光谱索引，r是张量与标量之比，N是电子折数。为了探索模型的参数空间，我们还进行了MCMC分析并找到$\alpha =7.56\pm 5.15$（1σ）。
