一、引言利用石英晶体的压电效应可以制成晶体振荡器。石英晶片(以下简称晶片)的谐振频率受晶片上附着(或去掉)质量的影响最灵敏的振动模式是高频厚度切变振动模式。厚度切变振动晶片的谐振频率由其频率方程决定。用压电石英谐振子定量测量 First, the introduction of the use of quartz crystal piezoelectric effect can be made crystal oscillator. Quartz crystal (hereinafter referred to as the wafer) by the resonant frequency of the wafer attached to (or removed) the quality of the most sensitive vibration mode is high-frequency thickness shear vibration mode. The resonant frequency of the thickness-shear vibrating wafer is determined by its frequency equation. Using piezoelectric quartz resonator quantitative measurement
