WANG Yong-sen1,2, CHEN Jian-sheng3, WANG Ji-yang4, TONG Haibin2, CHEN Liang5(1.State Key Laboratory of Hydrology-Water Resources and Hydraulic Engineering,Hohai University,Nanjing 210098,China;2.College of Hydrology and Water Resource,Hohai University,Najning 210098,China; 3.Reserch Institute of Science and Technology, Hohai University,Nanjing 210098,China; 4.Institute of Geology and Geophysics,CAS,Beijing 100029,China; 5.Geotechnical Research Institute of Hohai University,Nanjing 210098,China)  
The relationship between deuterium and oxygen18 in atmospheric precipitation shows the certain law.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.And the relationship between deuterium and oxygen18 in precipitation and clouds vapor is deducted.The result shows that it is not simply linear relation between the deuterium and oxygen18 in precipitation.
