摘要
由10个大雹块(长轴47—64mm)切片中的43个氘样分析得知:雹块的平均δD值为-93.8‰,其相应高度为海拔807m(-14.7℃),干生长层的平均δD值为-101.8‰,相应高度为8803m(-19.5℃),湿生长层的平均δD值为-91.5‰,相应高度为7413m(-11.4℃)。氘含量与冰晶平均长度之间有较好的统计关系。
The analysis of deuterium concentration on 10 giant Hailstone slices (major axis are 47- 64mm) shows the average deuterium concentration is -93.8 ‰ ; and its corresponding height is 8071 m .a . s. 1. (- 14.7 ℃ ). The average value of dry growth layers is -101.8‰ , and its corresponding height is 8803m. a. s. 1. (- 19.5 ℃ ); the average value of moist growth layers is -91.5‰, and the corresponding height is 7431m. a. s. 1. (- 11,4 ℃ ). There is a well statistical relationship between the deuterium concentration of growth layers and the average length of ice crystals.
