The main conclusions are as follows: ①The two digital instruments are stable. ②The observation data of the SWY-II instrument coincided with the LN-3A instrument. ③The measurement accuracy of two instruments is basically the same. There is a good identity in the mean consistency of the two instruments. ④There is little difference in the tidal factor of M2 wave and the observation precision between the two instruments. ⑤The two instruments have systematic drift in varying degrees. ⑥There is a big difference in the vibration time and the ranges of the water-seismic waves between the two instruments. ⑦There is little difference in the barometric effect and the natural environment interference between the two instruments. %R %U http://zgdz.eq-j.cn/zgdz/home %1 JIS Version 3.0.0
