用数字电桥测量介电材料与软磁材料的特性

Measuring the characteristics of dielectric and magnetically soft materials using digital bridge

应用数字电桥采用并联等效或串联等效方法测量了介电材料和软磁材料的特性,考察了BaTiO_3材料的复电容率及MnZn铁氧体材料的复数磁导率随频率的变化规律.

The characteristics of dielectric material and magnetically soft material were measured by digital bridge adopting the method of parallel equivalent or series equivalent.The changes of the complex permittivity of BaTiO3 and the complex permeability of MnZn ferrite with frequency were studied.
