摘　　要：对一个多矿物样品在BG2003释光谱仪上获得了包括红光、绿光和热释光的选频释光特征图谱,并求得样品不同激发方式下的等效剂量值和饱和剂量值,明确了不同激发方式下样品的不同波长可适用于年龄测定。同时与在热释光仪RGD-3B上求得的等效剂量值和饱和剂量进行了对比,两个饱和剂量值有很好的一致性(均为400Gy)。We have acquired characteristic spectra of a sample consisting of many minerals for the selected frequency luminescence using BG2003 spectronmeter stimulated with red light, green light of a laser source, and a heat source, respectively. And its DE and saturated dose can be obtained under different stimulation conditions. It is clear that different wavelengths can be adopted for dating. The saturated dose measured using BG2003 spectrometer was consistent with that measured using RGD-3D TL equipment, which was equal to 400 Gy.

关 键 词：特征释光图谱 等效剂量值
