【摘要】 本文简要回顾了222Rn及其子体示踪应用的主要方面,介绍了国内外对利用222Rn及其子体在预报地震和大气物质输运研究这两方面的工作。对这些示踪应用而言,要进行准确的定量分析和数值模拟,必须对222Rn及其子体在大气中的输运规律有细致的了解,这一点可以通过研究其动力学特征,建立输运模型来实现。本文中列举了部分对222Rn及其子体输运模式的研究,对比上层大气中的简单输运模型,一个比较全面的222Rn输运模型还需要考虑地表层结大气中的复杂的动力学因素,并将其作为222Rn在上层大气输运模型中的下垫面边界条件。更多还原

【Abstract】 222Rn and its progeny are widely applied as a tracer in many studies,mainly for the prediction of earthquake and atmosphere transportation of pollutants.Precise simulations on the transportation of 222Rn and its progeny,which could be deduced from their kinetic characteristics,are required.With respect to the kinetic model in the upper atmosphere,the perpendicular transport model for 222Rn in the near ground layer support a reasonable configuration as the bottom edge of the former.更多还原
