石英晶体的压电效应发现于1879年,利用其压电效应,通过一定的能量馈给,可以对不同切型和尺寸的石英晶体激起弹性振动。由于石英晶体的结构十分完整,而且其物理化学性能都相当稳定,并有很高的Q值,因此受其控制所得到的振荡器具有很高的频率稳定特性。最早的石英晶体振荡器应用大约在1920年左右,当初的振荡频率主要在较低的50千赫和
The piezoelectric effect of quartz crystal was discovered in 1879. With its piezoelectric effect, a certain energy feed can excite elastic vibration of quartz crystal with different types and sizes. Due to the crystal structure of quartz crystal is very complete, and its physical and chemical properties are quite stable, and have a high Q value, so the oscillator obtained by its control has a high frequency stability. The earliest application of quartz crystal oscillator about 1920 or so, the original oscillation frequency mainly in the lower 50 kHz and
