摘要
统计全国56个5.0级以上地震前109条水温观测数据的异常变化情况,分析其强度分布特征,将其作为水温仪器分辨力选择的重要参考依据之一。在此基础上采用同型号仪器在单井不同深度开展对比观测实验,得到不同噪声水平和扰动条件下仪器分辨力选择的量化依据。同时定量分析云南水温观测台网、龙陵水温观测台阵在传感器分辨力选择过程中的细节问题。结果表明,云南水温观测台网能够有效监测到震前异常变化信号,龙陵水温观测台阵中传感器分辨力与环境条件的匹配程度需作进一步调整。
We calculate the abnormal changes of water temperature observation data,which contain 56 earthquakes more than M_S5.0 all over the country.Then,we analyze the characteristics of intensity distribution,which can be used as one of the important references for selecting the resolution of water temperature instruments.Based on this,we carry out comparative observation experiments indifferent depths of a single well using the same type of instrument and analyzethe quantification basis of instrument resolution selectionunder different noise levels and disturbances.Meanwhile,we quantitatively analyze the selectiondetails of thesensor resolution of water temperature observation network in Yunnanand water temperature observation array in Longling.The results show that water temperature observation network in Yunnancan effectively monitor the abnormal change signals before earthquakes.However,the matching degree between the sensor resolutions and the environmental conditions of water temperature observation array in Longling should be further adjusted.
