平房仓粮堆温度时空分布的基本统计特征分析 总被引:3,自引:0,他引:3
在以2h等间隔不间断采样,采集了聊城1栋储藏小麦的和铜梁1栋储藏稻谷的平房仓近2年的粮情监测数据,在此基础上对平房仓粮堆温度分布的统计特征进行分析,得出平房仓粮堆温度时空变化的一些基本规律,并就其对传感器布局的影响进行了讨论。认为可以通过对最大温差变化点的跟踪分析,找到粮温异常点,并建议:①提供任意两次检测之间的温差,特殊标注其中10%的最大温差,并将其列入粮情检测系统标准;②加大现有设备的检测频率,以弥补现有检测点布局的不足。 相似文献

At the preliminary design stage of a building, it is neccssary to determine thebeam and column cross-sectional sizes of frame strtictures.According to some provisions of the"Building Aseismatic Design Code"(GBJ 11-89),main factors having influence on the beam andcolumn cross-sectional sizes are analyzed.and calculating formulas for the determination of the beam and column cross-sectional sizes which are satisfied the restrained condition of horizontal dis-placement of a building are derived in this paper. 相似文献
