摘　　要：濮阳市地震台经过观测仪器的数字化技术改造,使用SD-3A型数字化测氡仪开展了土氡数字化观测。观测结果显示,土氡集气装置的好坏对观测结果影响很大。对集气室装置存在的问题进行了改造,观测结果更好地反映了地下土氡的变化情况。研究了濮阳台土氡数字化观测资料的动态特征,结果表明:观测资料表现出明显的气压效应,土氡观测值与气压的影响成负相关关系。Digital soil Rn observation data recorded using SD-3A instrument in Puyang seismic station are studied. The result shows that： soil radon gas-collecting device have a great influence to observation re- sult. The gas-collecting device was reformed to solve the existing problems. After reforming, the quantity of the observation data is greatly imprrved. There is a negative correlation between observations of soil ra- don and air pressure.
