随着地震科技的发展,观测仪器需要不断地更新。近年来对土壤中氧气的测量研究应用越来越广泛。虽然测土氡的方法很多,但在地震系统α径迹法还在普遍的应用。径迹法存在着较多的不足,如埋片的时间长、片子小、取片后还要经过化学方法处理——蚀刻, With the development of earthquake science and technology, observation instruments need to be constantly updated. In recent years, the research on the measurement of oxygen in soil is more and more widely used. Although there are many ways to measure soil radon, the α-track method in seismic system is still widely used. There are many shortcomings of the track method, such as buried film for a long time, the film is small, after taking the film but also through chemical methods - etching,
