利用固体物理的理论分析,得到了磷灰石样品中α粒子核径迹密度与退火热量的关系。地质测年标准样品Durango磷灰石和长安大学采集的安徽马鞍山产出的磷灰石,用加热炉退火后,分别用α放射源和微型反应堆辐照,辐照后进行热分析曲线进行比对分析。由DSC曲线的形状、放热范围、峰值温度位置来看,两者为同一种粒子核径迹退火时放出的热量。用已知年代 Using the theoretical analysis of solid state physics, the relationship between the diameter of α-particle track and the heat of annealing in apatite samples was obtained. Geological dating standard samples Durango apatite and Chang'an University, Anhui Ma'anshan apatite produced by the annealing furnace, respectively, α radiation source and the micro-reactor irradiation, the radiation after the thermal analysis curve comparison analysis. Judging from the shape of the DSC curve, the exothermic range and the peak temperature, both are the heat released during the annealing of the same particle track. With the known age
