摘要
分别用ＮａＣｌＯ、ＮａＯＨ溶液、Ｎａ４Ｐ２Ｏ７和ＮａＯＨ混合溶液和有机溶剂对采自延庆盆地大王庄两个泥炭样品进行前处理，每个样品获得１０个不同有机组分，对这些有机组分的１４Ｃ年龄测定值进行对比。以探讨泥炭等样品不同有机组分１４Ｃ测年的可靠性。
Two peat samples collected from Dawangzhuang section, Yanqing basin were treated with NaClO, NaOH solution, Na 4P 2O 7 NaOH soultion and organic soultion, respectively and then ten different organic fractions were obtained from each peat sample. The radiocarbon age of each fraction was obtained and compared to evaluate the accuracy and reliability of the radiocarbon dating age of each fraction.
