1、Otherwise the daily mean is perturbed appreciably by the lunar constituents.

2、The heat resource is analyzed with the data of the daily mean temperature of the meteorological stations in Pengzhou city.

3、A new method for precursory information extraction, i. e. slope difference information method is proposed in the paper for the daily mean value precursory data sequence.

4、The daily mean values and anomalous maximum correlation coefficients suggest that the fluid anomalies appearing in the CCSD main hole might have a certain relation to seismic activities in the area.

5、The figure of daily mean value in resent year showed: the medium term anomaly with impulse jumps appeared 11 months before the event, and the maximum of anomaly was 84 times of the normal rising rate;

6、The drift of CZB-1 tiltmeter at Lanzhou Observatory is analyzed and studied in this paper. According to the drift tendency of daily mean values curve, the drift phenomena could be eliminated.
