摘　　要：对甘肃地区数字化流体观测资料的干扰因素进行了系统的分析。通过对观测资料的分析，发现影响因素大部分是仪器故障引起的，人为因素很少。水位、水温主要有仪器故障及性能影响、电压瞬间不稳（或遭雷击）干扰、无效数据、人为干扰、多个测项影响、数采器故障、传输、原因不明、观测环境干扰等。气氡（气汞）脱气-集气装置的好坏，对数字化气体观测起决定性作用，此外，闪烁室被污染、气路堵塞、漏气等可能引起显著的干扰，还有仪器性能不稳、电压不稳、人为因素等；另外，汞灯或光电倍增管老化、补汞管老化、抽气泵老化、抽气不稳定、泵膜老化、轴套磨损、室内有污染或仪器内气路被污染、抽取饱和蒸汽体积不标准都可能引起观测值的不正常变化。In this paper the interference factors of digital fluid observation data in Gansu province were systematically analyzed. According to analyzing the observation data, we found that the ma- jority of interference factors were caused by equipment failures, rarely by human factors. The da- ta of water level and water temperature were mainly disturbed by the equipment failure, voltage transient instability （or struck by lightning）, invalid data, and so on. The quality of degasser-- extractor devices of gas radon （gas mercury） played a decisive role in digital gas observation. Be- sides, contamination of scintillation chamber, gas circuit＇s blockage or leakage, as well as insta- bility performance of Instrument, voltage instability and human factors, may cause notable inter- ference. Some other factors can also cause abnormal changes of observed value.
