束缚电荷 meaning in Chinese

blowout electricity
bound charge
boundcharge
charge, bound

When piezoelectric material is put on outside force , it will cause the translocation of positive and negative electricity inside piezoelectric material . then piezoelectric material will generate polarization and shape tied electricity on the surface of the piezoelectric material that is proportional to the outside force
对压电材料施加外力时，会引起压电材料内部的正、负电荷发生位移，并产生极化，从而在压电材料的表面形成与外力成比例的束缚电荷，称为正压电效应。
