( 2 ) the mathematical model of corn drying was established and the solution was gained using the difference means . the humidity and temperature curves of corn drying were gained and the effect of a variety of factor to drying process was analyzed ( 2 )以玉米颗粒的干燥为例，用差分方法对所建模型进行求解，得到玉米颗粒干燥过程中内部含湿量和温度的变化曲线，并分析了各种因素对干燥过程的影响。
Using masson pine ( pinus massoniaha ) as specimen , experiments based on the research of water diffusion coefficient and floating coefficient have been carried out to reveal the fundamental principle of absorbed water movement in wood drying under vacuum - floating pressure 摘要该文以马尾松为试验材料，通过对水分扩散系数和浮压系数的试验研究，总结出木材在真空浮压干燥过程中吸着水迁移的基本规律。
The purpose of this thesis is devising a wood drying controller for wood drying kiln and other complicated control object . this paper applies fuzzy control technology to establish fuzzy model for wood drying kiln , and realize intelligent control of wood drying process 本文旨在设计一种基于木材干燥窑等复杂控制对象的控制器，应用模糊控制技术建立木材干燥窑模糊模型，实现木材干燥过程的智能控制。
Under the action of cycle fan , the hot air stream inside each unit of the dryer will carry out hot air cycle . final air with iow temperature and high damp will be out . the whole drying process with stably and high effect will be finished 使热空气穿流通过床面上的被干燥物料进行均匀的热质交换，机体各单元内热气流在循环风机的作用下进行热风循环，最后排出低温高湿度的空气、平稳高效地完成整个干燥过程
Based on studying of the documents about freeze - drying process and freeze - drying mathematical model , it is founded that a partial differential mathematical model of heat and mass transfer in the condition of entire radiation heating , and the application and solution of the models is also discussed 在对食品冷冻干燥过程及其数学模型文献深入研究的基础上，建立了纯辐射加热条件下传热、传质的偏微分数学模型，并对模型的求解及应用进行了讨论。
In the last years , scientists has had terrific progress and many study fruits in the subject of porous media ' s drying . however , the experiment was still primary study means in the subject for the process of porous media ' s drying was complicated , changeful , non - steady 多孔介质干燥学科发展到今天已经取得了长足的进展，研究成果众多，但由于多孔物料干燥过程的复杂性、多变性和非稳定性，使得对多孔介质干燥过程的研究仍然以实验研究为主。
