释光方法利用矿物晶体对环境辐射的响应关系 ,测定样品的总体吸收剂量 ,在考古与第四纪沉积物的年代测定方面有独特的优势 ,在油气勘探工作中也有较好的应用前景。 The light-emitting method takes advantage of the response of mineral crystal to environmental radiation and determines the total absorbed dose of the sample. It has unique advantages in the dating of archean and Quaternary sediments and also has good application prospects in oil and gas exploration.
