| Abstract: | Formulas for frequency temperature coefficiente of longitudinal modes and thickness modes of piezoelectric crystals of arbitrary cut are obtained by tensor and matrix clalculation. These temperature coefficients are calculated for lithium niobate,These obtained curves are helpful for use of the crystal. |
