摘　　要：采用了3种α放射性比的测定方法:几何级数法、外推法和曲线拟合法。检验了几何级数法的可靠性。把外推法、曲线拟合法的结果与几何级数法的结果作了比较。The paper describes three determination methods of alpha activity ratio used at our laboratory,namely geometric progression method, extrapolation method and curve fitting method. The validity ofthe geometric progression method is demonstrated in the present work. The ^(238)Pu/ (^(239)Pu+^(240)Pu) evalu-ated by extrapolation method is compared with that by geometric progression method. Also, the ^(238)Pu/(^(239)Pu+^(240)Pu) evaluated by curve fitting method method is compared with that by geometric progres-sion.
