  "abstract": "The nucleon-nucleon short-range correlation NN-SRC is one of the key issues of nuclear physics, which typically manifest themselves in high-momentum components of the nuclear momentum distributions. In this letter, the nuclear spectral functions based on the axially deformed relativistic mean-field model are developed to involve the NN-SRC. With the spectral functions, the inclusive electron scattering $ (e,e^{\\prime}) $ cross sections are calculated within the PWIA framework, including the quasi-elastic (QE) part and $ \\Delta $ production part. Especially in the $ \\Delta $ production region, we reconsider the electromagnetic structures of the nucleon resonance $ \\Delta $(1232) and the scattering mechanisms, thereby the theoretical calculations are improved effectively and the cross sections are well consistent with the experimental data. The theoretical $ (e,e^{\\prime}) $ cross sections are further divided into NN-SRC and mean-field contributions. It is found that, at the kinematics $ 0.5 \\,{\\rm GeV}^{2}<Q^{2}<1 \\,{\\rm GeV}^{2} $, the QE peak and $ \\Delta $ production peak not only reflect the mean-field structure, but also are sensitive to the NN-SRC information. Finally, we provide a new method to extract the strengths of NN-SRC from experimental cross sections for selected nuclei at the suitable kinematics.",
