remark：
(1)The data in the table are tested after polarizing ten days except ρand Tc
(2)The warp of ”ε” is ±12.6%, the warp of “s” is ±10%, the wrap of “N” is ±5%
(3)The data in the table is the character of piezoelectric ceramic material.
(4) The character of piezoelectric component can be calculated according as CB1194-88..
