摘要: The correlation between the EMC effect and progressively suppressed central density is explored within the T. D. Lee's soliton bag model and double \textit{Q}$^{2}$-rescaling model. It is found that as the central nuclear density progressively decreases, the average nucleon swelling factor and double \textit{Q}$^{2}$-rescaling parameters gradually diminish, consequently leading to a systematic reduction in the slope of the EMC ratio.
