| 摘 要： | 通过对江苏省大量台站地温数据相关特征的分析,找出最佳相关指标点随时间分布规律;介绍利用单站资料建立统计估计指标和经验估计指标,并对估计值与正确值的偏差情况进行比较和分析。结果表明:绝大多数情况下,两种指标所确立的估计值与正确值之差均在给定的科学合理范围。这一结果可作为日常判断地温传感器故障的重要依据。

| Abstract: | Based on the analysis on the related characteristics of enormous ground temperature data at observatories in Jiangsu Province,the general law of the appearing time of the best index point is found. With single-stationed data,the statistical index and empirical index are established and the deviation between estimated value and correct value is compared and analyzed.Conclusion is drawn as follows:In most cases,the deviation between the estimated value and correct value,which are established by the two indexe... |
