基于一种新颖的液体悬浮式长周期、超低频检测技术，避免电磁信号可能产生的一切干扰，由此研制地震前驱波检测装置及其分析软件。提取前驱波信号与实际地震进行比对分析，结果表明，利用该装置及分析软件，对于记录前驱波和地震预测研究较以往有新的收获。

By using a novel liquid suspension detection technology of long period and ultra-low-frequency to avoid all interference of electromagnetic signals that may be generated, seismic precursor wave detection device and its analysis software are researched. Precursor wave signals are extracted to be compared with actual earthquakes, analysis results on which show that application of the device and the analysis software has made aa new harvest in recording the earthquake precursor waves and earthquake prediction research.
