As the characteristics of SAW sensor are greatly influenced by temperature,these sensors have one acoustic path for reference another acoustic path for measurement in order to reduce the influence of temperature.

• 由于环境温度对SAW传感器性能影响显著，所以本论文研究的Y型和S型声表面波质量传感器件都具有两支声路，一支声路作为参考声路，另一支声路作为测量声路，以补偿环境温度的影响。
