| 摘 要： | 对ＥＳＫ测年样品的累积剂量和剂量率测量进行了讨论，并对化石样品年龄及其误差计算模式进行了探讨。对北京猿人洞牙化石釉质层的铡年研究表明，年龄数据稳定可靠，可与有关测年法结果对比。ＥＳＲ化石测年法已成为当前唯一能直接测定化石年龄大于４０万年的测年方法，对古人类演化研究具有重大意义。

| Abstract: | Electron spin resonance (ESR) dating has been developed since 1975. This paper discusses accumulated dose and dose rate,two indispensable parts of ESR dating,of fossil samples,as well as the early U-uptake and linear U-uptake calculation models and their errors. The results of ESR dating for the fossil tooth enamel from the Peking Man site show that ESR dating is reliable, and is comparable with other dating methods. It may date fossils older than 400000 years, therefore is very promising to archaeological study. |
