一、问题的提出目前国内外开展用水中氧含量的变化来预报地震,同其它手段一样,首先的工作是判断出异常形态的存在,尔后进行数据处理,异常形态有两种:一是趋势性的;二是临震性的.无论何种异常均有共同特点,即在观测曲线上都有较大的起伏,在数量上观测值均大于一定的特征值.曲线若出现与基线有较大偏离时,在排除了系统或非系统干扰及偶然误差后,可认为是反映了地震信息.
First, the issue put forward At home and abroad to carry out water changes in oxygen content to predict earthquakes, as with other means, the first job is to determine the existence of abnormal morphology, and then data processing, there are two abnormal morphology: First, the trend , And the second one is ephemeral.What kind of anomalies have the common feature is that there is a great fluctuation in the observation curve and the observed values are all larger than certain eigenvalues.If the curve appears larger than the baseline Deviation, in excluding the system or non-system interference and accidental errors, can be considered to reflect the seismic information.
