已经在大气 Ar/N2 和 O2/N2 混合物中检查了由 ZnO 和碳纳米结构电极系统中的宇宙射线电离引起的气态电子特性。测得准线性阶段的电导率达到10-11~10-10 S/m的水平，比没有纳米结构的样品高4~5个数量级，这是由宇宙射线电离频率增加108~1010倍来解释的。结果与以下假设一致：一维纳米结构在这种气态电子现象中的作用是基于强场梯度效应，而不是场增强效应。
Gaseous electronic characteristics due to cosmic ray ionization in the electrode systems with ZnO and carbon nanostructures have been examined in atmospheric Ar/N2 and O2/N2 mixtures. The electric conductivity at the quasi linear stage is measured at the level of 10-11~10-10 S/m, 4~5 orders of magnitudes higher than that of the samples without nanostructures, which is construed by the 108~1010 times increment of the cosmic ray ionization frequency. The results are consistent with the hypothesis that the role of one-dimensional nanostructures in this gaseous electronic phenomenon is based on the intensive field gradient effect, rather than the field enhancement effect.
