摘　　要：目的探究不同环境下密闭容器内微环境的变化规律。方法通过连续采集室内存放、户外遮盖、户外暴露3个包装容器内外11个监测点的温湿度数据,对比分析不同容器内温度、湿度的分布与变化规律。结果户外容器日间温度梯度大,昼夜温差高达30℃,温度波动远大于室内容器的1.1℃,篷布遮盖能降低20%的温度波动。容器内相对湿度不受环境湿度影响,但与温度强烈负相关。结论太阳辐射的热效应对包装容器内温湿度的变化与分布有决定性影响,应加强防护措施。In order to investigate the variation of micro-environment in airtight packaging container under different conditions,a container is placed in warehouse and two containers are placed outdoors,of which one is shielded while another is exposed.Eleven observation points are set to monitor their temperature and humidity.These data are compared and analyzed to reveal the variation rules.Results show that the outdoor container has large temperature gradient in daytime,and its temperature difference goes up to 30℃between day and night,which is far higher than the one in warehouse by 1.1℃.The temperature fluctuation can be reduced by 20%by covering with tarpaulin.The relative humidity inside the container is free from outer humidity,but it has intensive negative correlation with temperature.The thermal effect of solar radiation has determinative influence on temperature and humidity variation in outdoor containers,so protection measures should be strengthened.
