中文摘要：
介绍了一种测量电介质介电常数的新方法。以RLC串联谐振电路为基础,将平行板电容器与电阻、电感串联起来组成RLC振荡电路;当电路达到谐振状态时,电感已知,可测得平行板电容器的电容值,再根据平行板电容器的电容计算公式,间接测量出电介质的介电常数。此方法测量原理简单,操作方便,测量结果精确度较高,值得推广。
英文摘要：
A novel method for measuring dielectric constant was introduced. The RLC series resonant circuit as the foundation,the parallel plate capacitor and resistor,inductor in series RLC oscillating circuit; when the circuit of the resonant state,the inductance is known,can be measured in parallel plate capacitor capacitance value,then according to the calculation formula of the capacitance of parallel plate capacitor,the indirect measurement of dielectric permittivity.
