提出采用微孔滤膜对含有"氦氡团簇"的氡过滤,利用测量过滤后的氡浓度变化来研究"氦氡团簇"的粒径.对实验设计的合理性进行了详细论证.实验结果表明"氦氡团簇"直径小于100nm,与相关文献认为"氦氡团簇"粒径在100-400nm之间的结论不一致.

Propose an experiment method to study the diameter of helium-radon dusters by measure the filtered radon concentration which have been filtered the clusters by micro porous filtration membrane. The reasonableness of the Experimental design has been detailed feasibility studied The experiment shows that the diameter of helium-radon clusters are less than 100nm It differs from mutuality literature conclusion that the dia...
