摘要
研究表明，当α石英的平衡铀当量含量与其年龄之积远小于１时，Ｅ＇心浓度与年龄有线性关系．如果用其它方法准确测定了一个α石英样品的年龄并且用该样品作为标准样，那么待出α石英样品的年龄可根据其Ｅ＇心浓度比方便地求出。
A linear relation between the age of α-qusrtz and its E' centre concentration has been found when the Product at is far smaller than 1, where Q is the uranium content in equilibrium(g/g) and t is the age(Ma). This relation can be used to determine the age of α-quartz by measuring the E' centre concentration ther calibration with a reference sample.
