利用薄膜的透氧机理与油脂类氧化反应机理，推导出了标准状态下包装内氧气残留量的微分公式，借助此公式对各种防氧包装的影响因素及其效果进行了计算机模拟实验分析。 By using the mechanism of oxygen permeation and oxidation mechanism of grease, the differential formula of residual oxygen in the package under standard condition is deduced. The influencing factors and effects of various oxygen-proof packaging are simulated by computer simulation.
