摘要
裂变径迹退火过程是非线性动力学过程,在一系列磷灰石裂变径迹室内退火实验基础上,研究者提出许多经验退火模型,其中扇型模型与实验数据拟合最好,多组分退火模型将扇型模型的应用扩展到复杂物源成分的磷灰石.理论物理退火模型建立在原子尺度动力机制上,并经由实验数据确定具物理意义的未知参数,目前还不如经验模型成功.室内退火实验表明除了温度、受热时间,退火行为与磷灰石的化学成分,径迹与结晶c轴的方位关系、由Dpar定量表征的颗粒溶蚀度等因素有密切关系.
The process of fission track annealing is highly nonlinear. Based on a series of laboratory experiments on apatite fission track annealing many empirical annealing models are provided, among which fanning Arrhenius model is the best fitted and multikinetic model broaden its application to multiple composition apatite. The theoretical physical model is based on atomic-scale mechanism of apatite fission track annealing. Values for the unknown parameters in the physical model, each of which has a physical meaning , are founded through the experimental data . The theoretical physical model is not successful as empirical annealing models now. In addition to temperature and time , annealing behavior depends on apatite composition, angle between the crystallographic c axis and fission track and apatite solubility measured by Dpar.
