摘要
通过场的图形描绘法和实际测量,考虑平行板电容器边缘效应对电容测量值的影响并进行修正,从而获得对用交流电桥法测量纺织品等介质的介电常数的测量结果的修正。
Using the graphic depiction of the electric field and the actual measurement the influence of edge effect of a parallel plate capacitor on measurement result of the capacitance is considered and corrected. Thus the measurement result of permittivity of the dielectric like textile fabrics can also be corrected by the alternating electric bridge method.
