释光测年在应用研究方面的新进展

根据释光测年是地质学研究和考古学研究领域重要的研究手段和断代方法，总结出了在近十多年来应用该方法在以下几个方面所取得的成果及进展：（1）主要包括激发光源、晒退光源、辐射源以及操作软件等技术设备方面的巨大进展，以及由于释光测年技术设备精度的提高而由此极大地降低了释光测年的系统误差；（2）以单片再生测年技术和线性调整技术为代表的多种测年方法的快速发展，使得不同类型样品等效剂量的测定更加准确，而且测年流程更加简单易于操作；（3）测年材料不仅包括经受热过（主要是陶瓦）和经充足曝光的物质，同时对未经充足曝光的物质（如水积物和崩积物等）和其他经受热过的物质（如断层泥等）等也进行了大量的测年研究，从而极大地拓展了释光测年的应用领域；（4）各种年剂量测定方法的相互补充降低了在年剂量测定方面的不确定性．

New progresses of luminescence dating on application study

The luminescence dating is one of important research methods used in the study of geology and archeology.It has been made a rapid development in the last ten years,which mainly include:(1) the rapid progresses in the technical equipments,such as stimulating light source,bleaching light source,radiation source and operating software,etc..As a result,the dating precision of the technical equipment has been improved and the systematic error has been decreased largely;(2) the rapid progress in the dating method.As the developmental symbol of luminescence dating method,the single aliquot regenerative dose protocol and the linear modulation technique has been developed quickly in the last ten years,which turned out that the measurement of equal dose becomes more accuracy and its process is more simple and easily to operate;(3) the diversification of the materials for luminescence dating.It not only includes the heated materials(such as the fragment of ceramic and tile) and the complete optical exposure materials,but also includes the other heated materials(such as fault clay) and the incomplete optical exposure materials,which expands the application field of the luminescence dating;(4) the mutual complementation of the measurement methods for annual dose,which reduces the uncertainty in the measurement of the annual dose.
