摘要
Abstract
The harmonic analysis results of data by the YRY-2 bore hole earth strain meter of Tai-an seismic station from 1991 to 1996 are introduced.The dynamic characteristics and stability of the tidal parameters for the meter are analysed.A comparison between the results of the YRY-2 meter and SSY-Ⅱ quartz tube extensometer is made.The discrete error mean square of NS channel of the YRY-2 meter is 3.3 ％,that of NE channel of the meter is 3.6 ％,and monthly discrete error of phase lag is less than 2.0°.It shows the observation precision of the YRY-2 meter of the station is analogous to the best SSY-Ⅱ quartz tube extensometer.关键词
