本文根据河北省南部三个井孔近七年连续的二氧化碳测试资料,讨论了火车运样、室温、气温、气压、脱气、吸收等方面对测试精度的影响,从而制定了符合我省具体条件的工作方法。 对观测资料应用数理统计方法,确定室温是影响测试精度的主要因素。可用相关分析方法排除这种干扰,作为判别地震异常的基础。 According to the continuous carbon dioxide test data of three wellbores in the southern part of Hebei Province for the past seven years, the paper discussed the influence on the test precision of train borer, room temperature, air temperature, air pressure, degassing and absorption and so on, Working method Applied mathematical statistics to observed data to determine the room temperature is the main factor affecting the test accuracy. Relevant analysis methods can be used to eliminate this interference as a basis for discriminating seismic anomalies.
