摘要
控制温差是防止粮堆结露的关键,而结露温差的大小与粮食的水分有密切的关系。因此,找出二者之间的数学关系并适当地控制它们,是预防粮堆结露的根本措施。本文根据灰色系统理论的建模方法,计算出了粮食水分与结露温差之间的数学模型,模型具有较高的精度。
Controlling the temperature difference is the key of preventing the grain heap from being dewed. The bigness or smallness of the dewing temperature is closely related to the grain moisture content. So finding out the mathematical relation between the two and controlling them properly is the radical measure of preventing the grain heap from being dewed. According to the method of setting model of the grey system theory, this article has worked out the mathematical model between the grain moisture content and the dewing tem-prature difference and this model is very accurate.
