Zusammenfassung:	The invention discloses an oil paper insulation characteristic evaluation method based on liquid-solid interface concentration distribution, and relates to the technical field of environment-friendly transformer insulating oil development. Calculating density distribution parameters of mineral oil molecules and natural ester molecules at the interface of the cellulose paperboard by adopting molecular dynamics simulation; preparing mineral oil and natural ester oil-impregnated paper test samples, and performing thermal aging treatment on the prepared oil-impregnated paper test samples; carrying out polymerization degree test on mineral oil and natural ester oil-impregnated paper test samples treated at different aging times, and evaluating the anti-aging performance of the two kinds of oil-impregnated paper; and comparing and analyzing the evaluation result and the liquid-solid interface density distribution parameters obtained by simulation. The influence of thermal aging on the performance of two liquid-soli
