1Urey模型Urey(1947)模型或称之为Begeleisen-Mayer(1947)公式的建立,从统计力学理论上说明了计算同位素平衡分馏系数的方法,并且指出稳定同位素在地质上的重要作用,为稳定同位地球化学的发展奠定了重要的理论基础。对于如下一个简单的同位素交换平衡反应:ZY+Y’=ZY’+Y根据统
The establishment of Urey (1947) model or the formula of Begeleisen-Mayer (1947) in 1Urey model illustrates the method of calculating isotope equilibrium fractionation coefficient theoretically from statistical mechanics and points out the important role of stable isotope in geology. The development of geochemistry has laid an important theoretical foundation. For a simple isotope exchange equilibrium reaction as follows: ZY + Y ’= ZY’ + Y According to the system
