【摘要】 分析TJ-2型钻孔应变仪记录与测震仪记录的结果表明:该应变仪对于100 Hz的采样率有良好的频率响应,能够记录完整的地震波;从近震到极远震,其频响范围与测震仪基本一致,且频响的变化一致性很好,在一定的约束条件下,应变地震波与地震波在时域与频率域能够高度吻合;但该应变仪记录的S波较弱。更多还原

【Abstract】 On the basis of the analysis of high sample rate of borehole strainmeter data and comparison with seismograph data,we studied the characteristics of these datum.The results show that the TJ-2 borehole volume strainmeter with high sample rate has good frequency response with the 100 Hz sample rate;and it has the ability to record a complete seismic wave;also there are basically the same frequency response range no matter how long the distance from the epicenter,and the frequency response changes are consistent.The high sample rate strain seismic wave and seismic wave can be highly consistent in time domain and frequency domain under some constraint conditions;however,the strainmeter with high sample had a weak response to the S seismic wave.更多还原
