Interference factor analysis of the extensometer observation data at Korla Seismic Station
摘要
Abstract
The author analyzed various interference factors of the historical observation data of the extensometer at Korla Seismic Station and summarized main interference factors. The result shows that air pressure change influences on extensometer observation data obviously. The relation between observation data and air pressure is direct ratio. Other interference factors, such as meteorological factors (including air pressure, rain, wind and temperature), equipment failure, maintenance, power supply failure and human factor, are greatly effect on the observation data. Based on the analysis and recognition of the characteristics of data curve impacted by different interference factors, it suggests that it will be better to eliminate and reduce the interferences on the instrument for improving the quality of the observation data.关键词
