中文摘要：

选择3种具有代表性的贮藏设施通用温控仪表,检测其温度漂移幅度和方向。根据仪表电路原理并结合测试,进行了针对性电路改进,使温控仪表温漂误差幅度由3.5℃下降到0.3℃,贮藏环境温度波动幅度由5.3℃下降到1.4℃。试验筛选出3种简易温度补偿法,可在不改造仪表电路的前提下抑制温漂。

英文摘要：

Three typical farm products storage systems were adopted to detect the temperature drifts respectively.The cell circuit was improved according to the designing principal of the instrument electrocircuit.As the results,the error of the storage temperature was dramatically reduced from 3.5℃ to 0.3℃ and the cold storage temperature fluctuations decreased from 5.3℃ to 1.4℃.Besides,three simple temperature compensation methods were also selected.These methods were applicable to those places which were unsuitable for the instrument circuit improvement.
