利用美国依阿华大学J.L.Steele计算玉米贮存时二氧化碳产生量的公式和修正系数,以干物质分解量作为指标估计玉米的变质,用平衡方程计算玉米干燥过程,建立连续通风条件下,常温或低温玉米干燥与霉变过程的数学模型。并根据北京地区的天气资料,在计算机上进行了模拟,找出风量、初水分、损伤率对玉米霉变的影响,为玉米的安全贮存提供了依据。 Based on JLSteele from Iowa University, USA, the formula and the correction factor for calculating the amount of carbon dioxide produced during storage of corn were calculated. The amount of dry matter was used as an indicator to estimate the deterioration of corn. The equilibrium equation was used to calculate the drying process of corn. Under continuous ventilation, Mathematical model of drying and mildewing of corn. Based on the weather data in Beijing, the simulation was carried out on the computer to find out the effect of air volume, initial water content and damage rate on the mildew of corn, which provided the basis for the safe storage of corn.
