| Abstract: | The observation of the drill-hole strain meter aims at providing data with high quality for earthquake prediction. But interferes from observation environment are not avoided. The continuity rate and inner precise of data series are affected by these factors. How to recognize, to analyze and remove these affecting are very important to the data quality. |
