摘　　要：在分析粮堆内发热类型基础上,给出一维具有内热源非稳态导热情况等的假设条件以及思路.利用热力学定律、能量平衡理论等,以及借鉴其他领域比较成熟的方法,得出粮堆局部导热微分方程,建立了温度场变化数学模型,对粮堆内温度变化进行分析.以此有助于提高我国安全绿色储粮和质量监控技术.Some hypothesis conditions of one dimension for instability heat transfer with interior heating and thoughts are put forward in this paper based on analyzing the type of grain interior heating. With the law of thermodynamics and theory of energy balance, using mature method for reference in other field, the differential equation of heat transfer in the heap of grain is gotten, and mathematical model of temperature field is established. At the same time, the local temperature change is analyzed. The method might improve the technology of the safe storage and quality controlling of grain in our country.
