本文討論了BF_3气体天然硼同位素丰度的貭譜分析方法;測量結果B~(10)百分含量是19.37%;所获結果的貭譜分析測量精度为0.3%;着重討論了測量中貢献系統誤差的因素,有理由认为测量結果的准确度是在±1%范围之內。
In this paper, the method for analyzing the abundance of natural boron isotopes of BF 3 gas was discussed. The content of B 10 was 19.37%. The accuracy of the analytical results was 0.3%. The contribution of the contribution system The reason for the error, it is reasonable to assume that the accuracy of the measurement results is within ± 1%.
