中文摘要:本文利用滤膜法在静力扩散云室中,系统地测定了自然冰核活化数的湿度谱和温度谱,发现冰核浓度随温度降低而增加的规律必须满足一定的湿度条件,而且冰核增长的倍数远低于Fletecher的结果。根据测定资料对云室内的湿度场进行了检验,讨论了云室内冰核的活化机制,提出了因云室内滤膜收集的大量凝结核活化产生水汽消耗所引起的冰核浓度订正值的概量。
 
MEASUREMENTS OF SUPERSATURATION AND TEMPERATURE SPECTRA OF NATURAL ICE NUCLEI IN A STATIC VAPOUR-DIFFUSION CHAMBER
Abstract:Results of measurement of supersaturation and temperature spectra of natural ice nuclei in a static vapour-diffnsion are presented and analysed along with descriptions of certain humidity characteristics of the chamber and the nucleation mechanism therein. The underrating of and the correction for measured values by the filter method are also discussed.
