【摘要】 利用自行研制的NG-1000型和NG-2型稀有气体同位素比值质谱计测得3He／4He、4He／（20）Ne、4He／（40）Ar和（40）Ar／（36）Ar的比值用于地质研究和地震监测。测定了西藏羊八井地热区和长白山天池火山区的3He／4He和4He／（20）Ne比值，研究了这些地区逸出稀有气体的来源，连续监测了北京塔院断层土壤气4He／（20）Ne、4He／（40）Ar和（40）Ar／（36）Ar比值，并进行了地震预报的探索，获得了一些震例。更多还原

【Abstract】 The measuring method of rare gas isotope raios using the mass spectrometers developed by author for geology research and earthquake monitor is reported in the paper. We have measured 3He/4He and 4He/(20)Ne in Tibet Yangbajing Subterranean field and Changbaishan volcano field. The source of escaped rare gas in the two fields is researched. In addition, the continuouse monitor of 4He/(20) Ne. 4He/(40) Ar and (40)Ar/(36)Ar ratios in Taryun soil gas is carried out in order to study earthquake forecast. Some earthquake examples are obtained.更多还原
