Normal Dynamic Analysis of the Observational Results of Shanxi Tiltmeter Array

The observed data of tiltmeter array in Shanxi province are analized by the methods of Chebyshef fitting theory, first order difference, and γ factor dynamic analysis so as to obtain the observational accuracy, periodic interferential signals, and the background of normal dynamic variations which can be used as the indicators of working conditions as well as criterion seismic situations.
