Для акустических систем поверхностных волн используют термокомпенсированные пъезоэлектрические кристаллические элементы с по меньшей мере одной плоской поверхностью. Повышения термостабильности следует ожидать, если элемент кристалла состоит из YaPO4, а плоская поверхность определена углами Эйлера λ в области 0°, m в области 40-75°, предпочтительно 50-60°, и q в области 0°.For acoustic systems of surface waves, temperature-compensated piezoelectric crystal elements with at least one flat surface are used. Increased thermal stability should be expected if the crystal element consists of YaPO 4 , and the flat surface is determined by Euler angles λ in the region of 0 °, m in the region of 40-75 °, preferably 50-60 °, and q in the region of 0 °.
