摘　　要：分析了保山、庐江数字化气体流量观测干扰数据产生的原因,干扰数据的特点以及这些数据的实际意义,提出了剔除干扰数据方法,在数据分析和数据的使用中起到了较好效果。The observation technology of earthquake precursor has been improved greatly as the rapid development of science.The analogue record of earthquake precursor is replaced gradually by the digital record of earthquake precursor.Occasionally,the digitization data of the earthquake precursor changes greatly,because of the interference and the seismic precursor instrument.It becomes difficulty to analyze the interfered data.We analyze the reasons of the interfered Gaseous flow rate data in Lujiang and Baoshan seismic station,the characteristic of interfered Gaseous flow rate data,and the significance of the interfered data in the Gaseous flow rate data.Then,the paper also designs the way to eliminate the interfered data.This make it easy to analyze and use the gaseous flow rate data after the interfered data be eliminated.
