简要综述了最近十几争来稳定同位素地球化学基础理论发展的几个热点，包括能处理重元素的同位素分馏的核场效应理论、基于晶格动力学及声子的密度函数微扰理论计算的固体同位素分馏理论、稳定同位素的微观反应动力学理论，以及含压力变量的同位素分馏理论。这些新理论，表明长期基于Urey模型或称Bigeleisen-Mayer公式的稳定同位素地球化学的时代已经结束，更精确、更丰富的理论体系正在逐步建立之中。 |

Several hot and new directions of the theoretical stable isotope geochemistry have been briefly reviewed.These directions include the theory considering nuclear field shift can be used to study the heavy isotopes, the theory coupled with lattice dynamics and the DFPT method for phonon calculation, the isotope reaction kinetics and the theory incorporated with pressure variable. These under constructing new theories indicate that the era dominated only by the Urey model or Bigeleisen-Mayer equation is ended. More accurate and applicable theories are emerging. |
