摘要

对山东省水管仪、伸缩仪的数字化和模拟观测资料进行了对比分析。对资料的完整性、稳定性、可靠性进行了评价 ,并对资料的变化趋势、均值、方差一致性利用相关分析、t检验、F检验等方法进行了统计检验。观测资料在地震分析预报中的应用结果表明 :(1)水管仪、伸缩仪数字化观测资料的完整性、稳定性和可靠性优于模拟观测资料 ,数字化观测可代替模拟观测 ;(2 )水管仪、伸缩仪数字化和模拟观测资料的变化趋势一致性很好 ,均值、方差一致性较差 ,仅有个别测项一致。 (3)潮汐分析和非潮汐分析方法是识别强震前中短期和短临异常的可行方法。
This paper is about contrast and analysis of digital and analogic data of parallel observation with water tube tiltmeter and tensometer in Shandong province. The data was appraised in integrality,stability, reliability and the consistency of variational trend, mean, mean square deviation of data were statistically tested with correlation analysis, t-test,F-test etc.The application result of digital data in earthquake analysis and prediction shows that:(1)the integrality,stability and reliability of digital data of water tube tiltmeter and tensometer are better than the analog, so digital observation can be substituted for the analog;(2)the consistency of variational trend of digital and analogic observations of water tube tiltmeter and tensometer is very good, but the mean value and mean square are different to each other,only individual item is consistent.(3)the method of analysis of tide and analysis of non-tide are doable method that can distinguish the short-medium term and imminent short term anomalies before strong earthquake.
