| 摘 要： | 将黄土粒子直接撒入云室进行成核率检测，在–15℃时成核率可高达4×106/g。这些结果可解释在沙尘暴期间观测到的大气冰核的高浓度。从中国黄土高原扬起的沙尘粒子为下游地区提供了丰富的冰核。

| Abstract: | The ice nucleating effectiveness of the loess particles has been tested by directly dispersing them in cloud chamber. Their effectiveness can reach up 4×106 per gram at －15℃. From these results the high ice nuclei concentration observed during dust storms could be explained. It is considered that the airborne dust particles from the Loess Plateau of China would provide abundant ice nuclei for the downward area. |
