| 摘 要： | 地震流体观测在水资源过度开采的形势下,发展断层土壤气观测成为必然趋势.介绍了濮阳台土壤气氡观测的集气、导气装置,对濮阳台土壤气氡模拟观测及数字化观测结果进行分析.模拟观测与数字化观测结果有较大差异,分析产生差异的原因.提出采气率这个概念来定量衡量断层土壤气氡观测系统的实用效果.模拟观测和数字化观测结果与采气率有较好的对应关系,观测结果表明,集气室体积过大,会造成采气率太低,使观测结果偏低,气氡观测结果不适合进行地震前兆观测.在实际工作中, 要通过实验确定采气率的大小,设计合理的集气、导气装置,提高观测质量.

| Abstract: | It is necessary to develop fault soil gas observation along with earthquake fluid observation in situation of water excessive explotitation.The article introduces the collecting-transmitting gas device of Rn-observation in soil gases at Puyang Station and analyzes the simulation data and the digitized data.The simulation data and the digitized data are quite different.The concept collecting gas rate is proposed for the first time to judge the practical effect of the fault soil gas observation system quant... |
