摘要：

由谐振腔微扰理论出发,得到复介电常数计算式,测量了不同浓度的NaCl溶液及小鼠血液、肿瘤细胞悬液等样品的复介电常数;所得结果较为精确,证明了本测量系统的可靠性;对测量的系统、方法、仪器所引入的误差做了一定分析。

Abstract: Based on the perturbationtheory, got the measurement equations of the complex-permittivity, and measured the complexpermittivity of various NaCl solutions and blood of rat and tumor cell liquid etc.The result was exact relatively and the reliability of the system was verified;Made an analyse to the error result from measurement system、method and apparatus.

Keywords: Complex-permittivity; Perturbational method; Resonant-cavity; Measure
