Just there are more electricdomains more completely to turn to dispatch from foreign news agency field direction, external electronic field is big to reach saturation to the polarization for making material when allowing
Degree, i.e., when all electricdomain polarised directions are all fitly consistent with dispatch from foreign news agency field direction, after external electric field is removed, the polarization of electricdomain
Direction is basically unchanged, and material at this moment just has piezoelectric property, here it is the polarization process of piezoelectric ceramics.Piezoelectric ceramics polarization dress
It is exactly a kind of equipment for completing polarization process to put.
Existing piezoelectric sample polarization device, is mostly user and voluntarily builds, the design comparison in polarization clamp
It is coarse, it is impossible to which that sample of different shapes polarization in different directions is realized according to the size of the size of piezoelectric sample, this
Simple spring clamping mode is adopted mostly in outer prior art, clamping force is non-adjustable uncontrollable, is easily damaged piezoelectric examination
Sample.Therefore need a kind of demand, folder that different shape sample of different nature, satisfaction can be generally applicable to along different directions polarization
Hold reliable and adjustable controllable polarization clamp.
