摘　　要：以Peleg方程为依据,通过线性回归分析,计算式中的斜率K2和常数K1,利用实验测定水分含量与预测数据间的相对误差E进行拟合度的判定。建立了普通稻谷、高水分稻谷及糙米的吸水动力学方程,经检验,实验测定水分含量值与预测数据间的相对误差E均小于10%。可利用建立的浸泡吸水动力学方程对稻谷和糙米浸泡过程中的近似水分含量进行预测。Based on Peleg＇s equation,used linear regression analysis,the slope K2 and the constant K1 in the formula was calculated. Furthermore,the moisture content value and the percentage deviation modulus E between data was determinated and predicted by experiment,which could be used to judge the degree of fitting.The new water absorption equation of common paddy,high moisture content paddy and brown rice was established. Upon test,the moisture content value and the percentage deviation modulus E were less than 10%. The new soaking water absorption equation established could be used to predict the approximate moisture content of paddy and brown rice in the process of soaking.
