| 摘 要： | 利用热力学定理、传热学知识和能量平衡理论等，建立了粮仓谷物局部温度场变化数学模型，在初始条件和边界条件一定的情况下，求解数学模型中的微分方程时，发现微分方程的解不唯一。最后，利用实测数据验证了微分方程解的多值性与实际中粮堆内局部温度的多变性情况相符。

| Abstract: | The mathematic model of local temperature field of granary is founded by the thermodynamics theorem, heat exchange subject and law of energy conservation. The solutions of differential equation in the mathematic model are not unique, when the initial condition and confine condition are certain. Lastly, it is proved by the experimental data that multi-solution of the differential equation is accordant with the levity of the local temperature of granary. |
