假设凝结相和气相处于平衡状态，根据压力、温度以及云的平均氘氢比，可以计算出云中不同高度的水的氘氢比。人们收集了一颗冰雹，并测定了其连续各层的氘氢比。根据这些数值以及降雨期间大气垂直结构的相关知识，可以追踪这颗冰雹的“生命历程”。同位素分析的结果也与对同一场降雨中收集到的其他冰雹的照相分析结果进行了比较。对用于冰雹研究的同位素技术的进一步探索可能会得出其他重要结论。
The deuterium-hydrogen ratio of the water at various levels in a cloud can be computed from the pressure, the temperature, and the mean D/H ratio of the cloud, assuming that the condensed phase is in equilibrium with the vapor phase. A hailstone has been collected and the D/H ratio of the successive layers has been determined. From these values and the knowledge of the vertical structure of the atmosphere during the shower, the life history of the hailstone can be traced. The results of the isotopic analysis have also been compared with the photographic analysis of other hailstones collected from the same shower. A further exploration of the isotopic technique for the investigation of hail may lead to other important conclusions.
