【摘要】 对1995～2002年新沂台地电阻率和短水准进行对比分析,表明它们之间存在一定的相关性;同时在中强震之前,两者都有一定的异常与之对应。其相关性和地震对应性表明:由于是同场地观测,所受力源相同,造成异常变化量基本相同;但由于两者对应力变化反应结果不同,造成其异常出现存在不同程度的相位差,地电阻率出现的异常基本上早于短水准的异常。更多还原

【Abstract】 Through comparing and analyzing the short leveling and ground resistivity data at Xinyi station during 1995 -2002,it is found that certain dependence exists between them.In addition,both of them display certain anomalies before moderate-strong earthquakes.Correlation analyses indicate that because the short leveling and ground resistivity are observed at the same place and have the same stress sources,their anomaly values are almost the same.But since their responses to stress variations are different,phase differences to various extents exist between the anomalies of short leveling and ground resistivity,and normally the anomaly of ground resistivity tends to occur earlier than that of short leveling.更多还原
