These biosensors have usually poor stability and are prone to interference from environmental light, apart the high cost of quartz optical fibers for UV light transmission.
除了用作紫外光传输的高成本石英光纤之外，通常，这些生物传感器的稳定性都很差，容易和周围的环境光线产生相互干涉。
Especially, the use of SC cut quartz crystal further improves the short-term frequency stability and acceleration sensitivity.
尤其是石英晶体谐振片采用了SC切型进一步提高了短期频率稳定度和加速度灵敏度。
Most are crystal oscillators that take advantage of the inherent resonance of a (quartz) crystal to obtain frequency stability.
大多数是晶体振荡器，它利用(石英)晶体固有共振的优点，所以频率稳定。
