磷灰石裂变径迹退火影响因素研究进展

磷灰石裂变径迹退火是一个繁杂的化学动力学过程，清楚地了解其退火的影响因素对于该技术的应用十分重要。文章概述了磷灰石裂变径迹退火动力学模型的发展史，并结合以往对其退火影响因素的研究，将磷灰石裂变径迹退火影响因素分为自身和外部环境两方面：自身影响因素包括化学成分、晶体结构、径迹长度与半径、径迹与结晶轴的方位关系，其中化学成分对退火起到主导作用；外部环境影响中，温度是主导因素，压力和蚀刻条件的改变也会影响退火。研究成果有利于完善磷灰石裂变径迹的实验室退火模型，提高其作为热历史记录器的精度。

Research progress of factors affecting apatite fission track annealing

Apatite fission track annealing is a complicated chemical kinetic process. It is crucial for the application of fission track thermochronology to clearly understand the factors affecting annealing. In the article, the development of apatite fission track annealing model is summarized, and the research progress on factors influencing annealing is reviewed. Generally, the factors can be divided into internal and external ones. The internal factors include chemical composition, crystal structure, track length and radius, and crystallographic orientation, among which, chemical composition plays a leading role. Among the external factors, temperature is the dominant one, and pressure and etching conditions can also affect annealing. The research results are conducive to improving the apatite fission track annealing model and increase its accuracy as a thermal history recorder.
