| 摘 要： | 使用姑咱海子泉气氡观测数据，分析在不同脱气—集气（溅落式和自吸式）装置下观测数据的地震前兆异常反映。溅落式脱气装置在脱气过程中无空气混入，脱气效率较低，但地震前气氡观测异常明显；自吸式脱气装置在脱气过程中有大量空气混入，脱气效率相对较高，在地震前气氡异常不明显。分析认为：①空气混入起到稀释作用，致使气氡含量降低；②脱气装置前放置恒水位槽，将地震前泉水深部自然逸出气体释放，造成异常信息减少。

| Abstract: | By using the radon observation data of Haizi spring in Guza, we analyze the seismic precursor anomaly reflected by the observation data of different degassing-gathering gas (splash type and self-priming) devices. The splash type degassing device has no air mixing in the degassing process, the degassing efficiency is low, but the gas radon anomaly before the earthquake is obvious, the self-priming degassing device has a large amount of air in the degassing process, the degassing efficiency is relatively high, and the gas radon anomaly is not obvious before the earthquake. It is concluded that:① The mixing of air has diluted effect, and the radon content of gas is reduced;②The constant water level groove before the degassing unit will empty the natural escaping bubbles of the water pumped before the earthquake, resulting in the reduction of abnormal information. |
