泾县地震台DSQ数据固体潮分析

摘要

对泾县地震台 DSQ 型水管仪观测数据进行调和分析，认为倾斜仪工作比较稳定，观测资料质量达到形变规范要求；与往年同期数据调和分析结果进行对比，发现不同气候条件、噪声、地震等因素，均对调和分析结果，即相关潮汐参数有一定程度的影响。%The tidal effects on DSQ water tube tiltmeter is proved to be recorded completely through fast Fourier transformation to the raw data. Besides,it is assessed that the DSQ water tube tiltmeter runs stably through harmonic analysis of the data of the tilt tide recorded by DSQ water tube tiltmeter at Jingxian Seismic Station. The quality of the observations reaches relative specification requirements. Through comparative analysis of the harmonic analysis results between the data of the same period in different years,it can be concluded that different climatic conditions,noise and even earthquake will affect the tidal wave parameters.
