【摘要】 对铁岭粮食集团直属储备库有限公司P7平房仓储藏的稻谷开展粮温检测试验。在获取详实粮温数据的基础上，开展了粮温变化拟合曲线研究。发现稻谷储藏温度变化拟合成二次多项式曲线，拟合性较好。一年之中，粮温二次多项式拟合曲线应分为5月份前和5月份后两段。粮堆不同部位的粮温拟合曲线不同，应分别建立拟合曲线。为形成有效比较，应以记录日期在全年中的排序数绘制散点图及拟合曲线。更多还原

【Abstract】 The grain temperature test was carried out on the paddy stored in the P7 bungalow warehouse of Grain Depot Directly under Tieling Grain Group. Based on the detailed grain temperature data, the fitting curves of grain temperature changes were studied. And it was found that the quadratic polynomial curve was fitted well to the changes of paddy storage temperature. In a year, the quadratic polynomial fitting curve of grain temperature should be divided into two sections before and after May. Grain temperature fitting curves for different parts of the grain heap are different and should be established separately.To form an effective comparison, scatter plot and fitting curve should be drawn based on the date number of records in the whole year.更多还原
