| 摘 要： | 本文利用连续气流纵向热梯度云凝结核仪对太原的云凝结核（CCN）进行了观测研究。结果表明，CCN数浓度具有明显的日变化特征。CCN数浓度一天中出现了两次峰值。降水、降雪对地面CCN具有明显的冲刷作用。本文根据关系式N=CS#拟合得到的地面CCN活化谱参数C值明显较大，k值较高，属于典型的大陆型核谱。

| Abstract: | Observe and research the cloud condensation nuclei （CCN） in Taiyuan city by a continuous flow vertical thermal gradient cloud condensation nuclei instrument. The results show the concentration of CCN has a significant daily variation. The concentration of CCN deposited twice a day peak. Precipitation and snow have an obvious effect CCN on the ground it can reach 80. Based on the relationship N= CSK, the activation spectrum parameter C of CCN on the ground were fitted and it was significantly larger and it was typical of continental core spectrum. |
