| 摘 要： | 山东长清台数字化体应变仪观测曲线自1999年以来出现几次形态类似的大幅度突跳,为正确认识这类现象,在长清台做了交直流切换对观测值影响试验,并对水位、气压资料进行综合分析。研究结果表明,水位、气压、电源切换等因素不会引起体应变仪观测曲线的突跳。对比其他类似观测分析推测,这类突跳可能与“慢地震”事件或“岩孔崩落”现象有关。

| Abstract: | The observed data of the body-strain meter at Changqing Station in Shandong Province, occurred several times of similar sudden jump with large amplitude. In order to recognize the phenomena, we conducted a test about the switchover of the alternating current and direct current, and analyzed synthetically the data of the water level, and atmospheric pressure. The results show that all the water level, the atmospheric pressure and the switch of the power supply cannot cause the sudden jump of the observed data. Compared with other similar observations, we consider that such jump may be related with the "slow earthquake" events or the "bore-hole collapsing". |
