| 摘 要： | 选择中国不同地区的冲洪积相等水成相沉积物样品,根据其简单多片再生法(SMAR)测量数据建立了细颗粒石英光释光信号的综合生长曲线(Standardised growth curves,SGC)。对未知年龄的水成相沉积物细颗粒石英样品,通过测量其天然光释光信号和试验剂量响应信号,并利用上述SGC方程可计算出其等效剂量值。将此值与简单多片再生法(SMAR)测量结果相比较,统计得出对于天然等效剂量为12~65Gy的样品,其误差可达19%;对于天然剂量>65Gy的样品,其误差更大;对于等效剂量<12Gy的样品,最大误差也达25%。实验表明,应用这个SGC估计未知年龄样品的等效剂量值范围,再对样品采用简单多片再生法(或单片再生法)进一步测量,可大大节省测量时间

| Abstract: | Some water-lain sediments samples with different ages were selected from several regions in China,and their Standardized Growth Curves(SGC)were constructed for fine-grained quartz OSL signals that were measured by sensitivity-corrected multiple aliquot regenerative-dose protocol(SMAR).The equivalent dose of each sample can be determined by plotting their standard OSL intensity((LN/TN)TD)into the SGC curve.To estimate the reliability of this method in water lain sediments,their SGC ED values were compared to |
