We explore the superconducting pairing mechanism in the trilayer ${\mathrm{La}}_4{\mathrm{Ni}}_3{\mathrm{O}}_{10}$ material through self-consistent mean-field calculations. Our findings demonstrate that the intralayer pairing is substantially weaker compared to the interlayer one. Remarkably, in the superconducting state characterized by the interlayer pairing, our results indicate the presence of a partially gapped Fermi surface, a fascinating occurrence attributable to the inequivalence between the inner and outer conducting layers of ${\mathrm{La}}_4{\mathrm{Ni}}_3{\mathrm{O}}_{10}$. Moreover, this Letter provides valuable insights into the lower superconducting transition temperature observed in the ${\mathrm{La}}_4{\mathrm{Ni}}_3{\mathrm{O}}_{10}$ compound, thereby deepening our understanding of its distinctive superconducting properties.
