摘 要:为了给新疆阿克苏断层氢观测中干扰的识别、异常的判定、数据的分析及站点的建设提供参考和帮助,通过对阿克苏断层氢观测中气象、人为、供电、观测系统等干扰,分别从干扰形态、相关性、干扰幅度及影响时长等方面进行系统分析和总结,并对典型的供电干扰开展相关实验研究。可以看出,不同干扰因素的变化特征明显,在日常观测中通过系统的对比和分析较容易区别;通过对典型供电干扰开展的相关实验来看,供电所引起断层氢浓度值上升变化的主要因素来自UPS对蓄电池充放电的影响,供电干扰所引起断层氢上升变化的特点表现为:持续时间和上升幅度相对有限,持续时间一般在20 h内,上升幅度同观测背景值具有相关性。In order to provide reference and help for the identification of interference,the determination of anomalies,the analysis of data and the construction of stations in the fault hydrogen observation of Akesu in Xinjiang,through the interference of meteorology,man-made,power supply and observation system in the fault hydrogen observation of Akesu,the system analysis and summary are carried out from the aspects of interference form,correlation,interference amplitude and influence duration,and the typical power supply interference is carried out.It can be seen that the variation characteristics of different interference factors are obvious,and it is easier to distinguish them through systematic comparison and analysis in daily observation.According to the relevant experiments on typical power supply interference,the main factor of the increase of fault hydrogen concentration caused by power supply comes from the influence of UPS on the charge and discharge of storage battery.The characteristics of the increase of fault hydrogen concentration caused by power supply interference are as follows:the duration and the increase amplitude are relatively limited,the duration is generally within 20 h,and the increase amplitude is correlated with the observed background value.
