本文介绍了对北美大陆的水以及与该大陆相邻的表层海洋水中氘分布的1000多次分析所得到的探索性数据。阐述了似乎可以解释天然水中氘含量变化的过程的基本理论。针对水文循环的各个阶段，从海洋水的蒸发、雨雪形式的降水，到其回流至海洋，给出了可能发生的氘分馏的定量表达式。还讨论了诸如在平衡和非平衡条件下水的冻结、封闭湖泊以及有出水口湖泊的水蒸发、雾、霜和露水的形成等过程。描述并解释了北美地表水的区域特征，认为其反映了水文循环过程中水的历史。（作者）
Exploratory dnta from more than 1000 analyses of the distribution of deuterium in waters of the North American continent and the surface oceans contiguous to the continent are presented. The elementary theory of the processes that appear to explain the changes in the deuterium content of natural waters is developed. Quantitntive expressions of the deuterium fractionation thnt can be expected to occur are presented for all phases of the hydrologic cycle from the evaporation of wnter from the oceans, its precipitation as rain and snow, and its travel back to the sea. Processes such as the freezing of water under equilibrium and nonequilibrium conditions, the evaporation of water from closed lakes and from lakes with an outlet, the formntion of fog, frost, and dew are also discussed. The regional characteristics of the surface waters of Nonth America are described and interpreted as reflecting the history of the water in the course of the hydrologic cycle. (auth)
