32 ghz to 1 . 91ghz . the complex permittivity peak of nanometer siox and two dielectric losses of cnts are discovered in our experiment which are different from properties of other nanometer materials . we should do the further research to reveal the truth 在本实验的工作中发现与其它纳米材料不同的现象，纳米氧化硅的介电常数出现峰值，碳纳米管有两个介电损耗峰，建议以后的工作对其原因进行分析。
