| Abstract: | Data ,from Oct.1 2001 to Dec. 31 2001 ,of digital DSQ water tube tiltmeter in Zhengzhou Observatory of Henan was processed and analyzed and an observation accuracy assessment for this meter was made. The calculated results show the daily pharoses, amplitude factor of M 2 wave and mid-error of amplitude factor is 0 0007 second,0 7149 and 0 0055 for NS component respectively and 0 0026 second,0 6414 and 0 0044 for EW component respectively. |
