摘要：

1985年11月～1987年1月中国第二次南极考察期间,在长城站设立了冰雪晶观察点,对长城站区全年的雪情进行了监测。共捕捉到6次与冰雪晶有关的降雪过程,收集到4大类19个亚类的303张不同晶形的冰雪晶显微照片。对这些样片的时间序列分析表明,长城站上空云体中具有泡状结构,过冷水密度也存在某种分布。

Abstract:

During the second Antarctic Research Expedition of China (Dec. 1985 to Jen. 1987), the snow crystals was sampled at the Great Wall Station of China. There are altogether 303 samples collected through this year. They are belong to four races and nineteen subraces respectively. Time serise analyses evidence that the supercold water of the cloud related with those snow events has a certain bubble structure.
