利用关丙军法、趋势面分析法、双参考曲线法、三角化法和相关法等多种方法重建了1953-2002年北京地区的氚时间序列。通过将重建的结果与北京的测量数据以及IAEA GNIP数据库中的其他地区的数据进行比较，建立了北京1953-2002年期间的相应时间序列，并选择了最优的时间序列。重建结果可用于北京及周边地区地下水测年及相关研究。
Tritium time series for precipitation in Beijing have been reconstructed for the period 1953-2002 using various methods: Guanbingjun method; trend surface analysis method; double reference curve method; triangulation method; and correlation method. By comparing the reconstructed results with the measured data of Beijing as well as data of other regions available in the IAEA GNIP database, the corresponding tritium time series have been developed for Beijing for the period 1953-2002, and the optimal time series was selected. The reconstructed result can be used for groundwater dating and related studies in Beijing as well as the surrounding areas.
