| Abstract: | In order to analyze the influence of improving the sampling rate of strain observation and expanding the observation frequency band on low-frequency observation, we select the TJ-2 volume borehole strain meter to carry out comparative observations at Zhangjiakou and Huailai seismic stations. We analyze the experimental data in time and frequency domains, and summarize the relationship between the characteristics of volume strain and seismic observation frequency band. |

| Keywords: | deformation observation high sampling rate comparative observation observation frequency band |
