【摘要】 <正> 热释光方法是人们发现某些矿物有受热激发而发光的现象后,随着光电探测技术的发展而建立起来的一种方法。在研究矿物晶体所发出光子的能量时,人们感兴趣的是来源于天然放射性体系的衰变,例如铀、钍、钾,以及宇宙射线所贡献的那部分能量。而对非放射性体系所导致的能量或光子的更多还原

【Abstract】 Determining the absolute dates of specimens by means of thermoluminescent analysis is an important method to the dating of cultural relics unearthed from archaeological explorations. Using the fine-grain thermoluminescent method, the authors analyzed ancient ceramics unearthed from two sites of capital construction in Changsha City. They obtained 15 dates, of which the relative errors account for 8% and two data are unacceptable. Research on the factors of the errors indicates that the application of thermoluminescent analysis in the dating of specimens requires some preconditions and that the fine-grain method, therefore, has its limitations.更多还原
