摘要
本文主要介绍了地面辐射温度测量和地下不同深度的温度测量方法及结果，同时对地下输油 管道产生的热异常成因机理进行了初步探讨。根据测试结果分析了热红外扫描成像有利的时间和 季节；讨论了异常强度及地温的垂直衰减幅度；进行了温度梯度与热流值计算；总结了地下输油 管道上覆土壤的热传导作用在夜间的变化规律。
This paper introduces mainly the method and results of measurement of surface radiance temperature and ground temperature in different depths for research on the mechanism of thermal anomaly induced by ground oil-piping. The optimum time and season for thermal infrared scanning imaging is analysed based on the results of measurement. The anomaly intensity and vertical attenuation amplitude of ground temperature are discussed in it. The temperature gradient and thermal flow value are computed. The changing few of thermal transmission caused by ground oil--piping at night is discussed.
