摘　　要：1991年5月用滤膜法分别在南京北郊和内蒙东胜，进行了冰核的观测，得出了东胜平均冰核浓度比南京每升多0．05个。冰核浓度随活化温度的降低呈指数增加。降水、风等气象因子对大气冰核有一定的影响。In May 1991,using millipore, filters the concentration of atmospheric ice nucleus were observed in nothern outskirts of Nanjing and Dongsheng of Inner Mongolia separately. By calculating and analysing some results are gained,which show that the figures of ice nucleus in Dongsheng are O. O5 per litre more than those in Nanjing,the concentration increases with the decline of active temperature according to the exponential law and is influenced by meteorological elements such as precipitation and wind.
