【Abstract】 Considering that the testing atmosphere will directly affect the defect structure and electrical performance of the materials,a new type of testing system for dielectric temperature characteristic of dielectrics in various atmospheres has been designed and developed.The test system provides the automated measurement of dielectric characteristics with temperature in different atmosphere(Oxidizing,neutral or reducing atmosphere).The experimental results show that dielectric properties are strongly dependent on the atmospheres.The method provides a simple and effective way for the synthesis of complicated structural defects and polarization mechanism.更多还原
