The basic concept of isotope fractionation and the mechanism of Rayleigh fractionation model under equilibrium condition are discussed.
本文简要介绍了同位素分馏的基本概念,对平衡条件下瑞利分馏机制进行了分析。
This paper analyzes the impact factors for fractionation coefficient in Rayleigh fractionation, gives the differential equation models of stable isotope composition in precipitation in the open system and closed system,and discloses the variation law of deuterium and oxygen18 in precipitation.
大气降水过程中氢氧稳定同位素比值呈现一定的规律,分析了瑞利分馏中分馏系数的影响因子,基于瑞利分馏原理和质量守恒定律,分别推导了开放系统和封闭系统降水过程中的稳定同位素微分方程模型,研究了大气降水过程中氢、氧稳定同位素变化规律,导出了云团水汽和降水氢、氧之间的相互关系,结果表明这一关系并非简单的线性关系。
Having noticed its drawbacks and made some assumptions and simplifications,the following two models are deduced based on basic law of hydraulics and Rayleigh fractional principle:(1)the differential equation model for the stable isotope composition that varies with time in static water body,which discloses the relationship among stable isotope composition in static water body,the fractional.
针对其不足,在作了一定的假定和简化的前提下,基于瑞利分馏原理和水力学基本定律分别推导了:①静止水体的氢氧稳定同位素组成随时间变化的微分方程模型,揭示了静止水体的同位素组成与时间、分馏系数和蒸发率之间的关系;②河道中运动水体的同位素组成随时间和空间变化的微分方程模型,导出了河道运动水体中稳定同位素组成与分馏系数、流速、流量、蒸发率之间的定量关系。
