摘要
在用前剂量法作古陶瓷真伪鉴定的过程中 ,需要对样本加入多次不同量值的剂量再进行激活及熄灭效应的测试 ,从而加大了测量误差值 (通常都达 2 0 %— 30 % )。为了提高鉴定度 ,本文采用以固定剂量的熄灭效应作为参考值 ,以数学式子表达过程中发光强度的变化 ,并用几个测试序列作对比 ,找出比较理想的测试顺序。测量结果误差接近 10 % ,远比原来方法优越。结论是此方法是可行的 ,但仍需作更多的实际测量工作来肯定。
Pre-dose method normally requires several times of artificial doses been added to the sample (test dose or calibrated dose) to process the thermo-activation, thermoluminesence and quenching effect. The error of the measurement usually increases with multiple procedure and dose adding (about 20%-30%). In order to increase the accuracy of the dating, this article selected a constant dose value as a reference of thermoluminesence and quenching effect. Using different testing procedures to evaluate the change in luminous intensity (sensitivity) by a set of mathematical equations. The best testing procedures are selected to minmize the error. The error can be reduced to almost 10% which is much better than the original dating method. The testing method is feasible but further works are necessary to testify, the conclusion.
