摘　　要：在各种干燥条件下（包括热空气的温度、湿度、干燥时间）进行了水稻的爆腰率试验。以干燥常数Ｋ为媒介，建立了干燥条件与水稻干燥爆腰增率Ｃ之间的数学模型：Ｃ＝６．６４９＋０．４５３ｔ＋（６．７４９＋０．１５０ｔ）［１．７４６－０．０３９（ＲＨ）－５７．９７４／Ｔ］。结果表明模型预测值与实验测定值相吻合。The experiment of paddy crack additional percentage (CAP) subject to various drying condition (drying conditions) including hot air temperature , relative humidity and drying time was done. Taking drying constant K as the media, the mathematical model between drying conditions and crack additional percentage was developed as follows: C=6.649+0.453 t+(6.749+0.150 t).974/T]. Its validity was checked by comparing simulated and experimental values.
