    摘要: Quartz crystal resonators 30 with a first angle of rotation having an X-axis 17 and Z′-axis 19 lying within a plane corresponding to an AT-cut and a second angle of rotation 34 within the plane of the AT-cut and lying within a range of about ±1° to about ±11.5° from the Z′-axis of the AT-cut. The resonators includes substantially opposing electrodes 36 disposed on major faces of the quartz crystal plate 32. The second angle of rotation 34 results in quartz crystal resonators 30 being produced with a more uniform distribution of temperature performances.
