石英晶体是不是振荡器？

Quartz crystals are used in circuits where a very accurate and constant frequency is required, e.g. in most transmitters, in clocks, microcontrollers, cell phones, computers as well as in frequency counters and digital signal generators.

石英晶体用于需要非常精确和恒定频率的电路中，例如大多数发射机、时钟、微控制器、手机、计算机以及频率计数器和数字信号发生器。

A quartz crystal alone determines only the frequency. Since a quartz crystal in itself is neither an oscillator nor a clock generator, it must be operated in an appropriate circuit to represent a crystal-stabilized oscillator circuit (crystal oscillator).

石英晶体本身只决定频率。石英晶体本身既不是振荡器，也不是时钟发生器，它必须在合适配置电路中才能代表晶体振荡器稳定的工作。

什么是石英晶体？

A quartz crystal is based on an artificial quartz crystal and serves as an electronic component for oscillator circuits, generating electrical oscillations with a defined frequency. Its operation is based on the principle of electromechanical resonance of the installed piezo-electric and quartz crystal contacted with electrodes.

石英晶体以人造石英晶体为基础，用作振荡器电路的电子元件，其作用是产生具有限定频率的电振荡。它的工作原理是基于石英晶体本身的压电特性和石英晶体与电极接触的机电共振原理。

Due to the piezo-electric properties of quartz, it performs precisely defined oscillations (resonance) under the influence of alternating electrical voltages. Electrically, the quartz then behaves like an oscillating circuit with high Q and thus acts as a clock generator in many applications with the appropriate circuitry.

由于石英晶体的压电特性，它在交流电压的影响下执行精确定义的振荡（共振）。在电气上，石英晶体的行为类似于具有高Q值的振荡电路，因此在许多具有适当电路的应用中充当时钟发生器。
