摘要
研究了牙珐琅化石的ＥＳＲ信号对辐照剂量的响应关系，讨论了用指数目数拟合定牙珐琅累积剂量ＡＤ的适用范围和所产生的系统误差的大小，并以郧县古人类遗址牙珐琅样品为实例检验了上述研究结果．
An experimental study has been carried out on the ESR intensity repoonse to irradiation. The systematic error of accumulated dose AD with the simple exponential function is evaluated. It is concluded that the systematic error depends on the AD value itself. The AD values and ages of 8 enamel fossil samples collectedfrom Yunxian Palaeoanthropological Site are determined to verify the conclusion.
