| 摘 要： | 本文着重阐述了已通过国家科技部验收的国家“九五”重点科技攻关计划项目-智能化粮情检测分析控制系统专题（96-615-05-02）实施过程中,使用统计软件SAS对辽宁沈阳,丹东,广西梧州,河南漯河等粮库的粮情检测数据进行分析的方法及结果。通过对粮堆温度与大气温度资料进行的相关分析。结果表明粮堆温度与大气温度间存在着明显的相关关系。但这种相关关系并非是纯线性的,而是随着测温点位置的不同,粮堆温度的变化表现出相对大气温度变化的滞后,这一相关系数随着测温点位置与外界距离的加大而呈现出递减趋势。

| Abstract: | The subject on intellectualized system for grain storage detecting and c ontrolling(96-615-05-02),part of a "Ninth Five-Year-Plan Project"has been checked and accepted by Mini stry of Scien-tific and Technology.During its imp lementation,the popular statistical analysis so ftware SAS is used to analyze the detected grain temperature data from several grain depots in Shenyang,Dandong,Wuzhou and Luohe city.The result showed that th ere do exist evident correlation between grain temperature and atmospheric temperature.But the co rrelation is not of pure linearity.A s the distance between the grain -temperature -detect point and outside increase,the change of grain temp erature show some lag to that of atmospheric temperature.And the correlation coefficient declines as t he distance increases. |
