一、厚度剪切模压电振子的制备这里,简述在1兆赫以上的高频内使用的厚度剪切模压电振子的制法。以前的厚度剪切模振子,为使其沿厚度方向产生剪切振动,如图1所示,需要在与压电板1的主平面相平行的A方向进行极化,这样,就必须在与极化
I. Preparation of Thickness Shear Molded Piezoelectric Element Here, a brief description is given of the method of making a thick sheared piezoelectric vibrator used in a high frequency above 1 MHz. The conventional thickness shear mode vibrator needs to be polarized in the A direction parallel to the principal plane of the piezoelectric plate 1 as shown in FIG. 1 so that shear vibration occurs in the thickness direction. In this case, polarization
