| 摘 要： | 以满城-任丘剖面为例,采用过剩空气非分馏(UA)模型进行了单独He成分的分离,第三含水组中含有的过剩4He是含水组(Q2)内原地产量和地壳通量的综合结果.由于缺乏确定He平衡参数的约束条件,选择了应用地下水流模型主观调节来估算迭代过程中外部通量和流速场,然后根据这个模型所取得的4He年龄与应用其他方法包括14C测年和水文模型取得的年龄作对比,取得了河北平原第三含水组满城-任丘地下水的4He年龄为0～30 ka的结果. |

| Abstract: | In this paper,the separation of the individual helium components has been performed with the unfractionated excess air(UA) model.The excess()~(4)He contained in third aquifer group is a crustal flux into the aquifer group(Q_(2)).Lacking the possibility of a well-constrained objective analysis of the parameters determining the He balance,the external flux and the velocity field are estimated in an iterative process using subjective tuning of a groundwater flow model.The()~(4)He ages obtained from this model are then compared to ages derived by using other methods including()~(14)C dating and hydrological modeling. |
