| 摘 要： | 对临汾中心地震台“十五”前兆观测系统运行情况进行了统计分析，结果表明：该观测系统工作状态稳定、运转情况良好，产出数据的连续率、完整率等指标达到了规范中≥95％的要求；3套形变观测数据“内精度”达到了国家“Ⅰ”类形变台的标准，对于全球7级以上地震和全国6级左右地震，石英摆倾斜仪能清晰记录到50％以上地震的前驱波现象；在同一地震前垂直摆出现的异常变化与石英摆存在截然不同的异常图像形态，这可能与两仪器自身之间的摆系、工作周期、频率等指标的差异性有关；大地电场有较好的远场异常效应，在青海海西等地震前记录到了明显的短临异常。

| Abstract: | The operation situation of precursor observation system of Linfen central seismological station constructed in 10th five-year plan is analyzed statistically in this paper.The results indicate that the observation system works well and stably,and the indexes of producing data,such as continuous rate and integrity rate,are larger than 95 percent,met with criterion request.The intrinsic precision of three types of deformation observation data reaches the criterion of the first class of national deformation sta... |
