对石英压力压电敏感器件的原理分析表明:这种敏感器达到热平衡状态具有相当长的时间常数,大约一小时量级。在这种情况下,再也不能忽略敏感器件的温度随压力的变化关系。当人们一旦需要使用精密敏感器件时,使要考虑到这一关系;本文将论及这一函数关系。 The principle analysis of quartz pressure-sensitive piezoelectric devices shows that the sensor reaches a very long time constant in thermal equilibrium, on the order of one hour. In this case, the temperature of the sensitive device can no longer be neglected. When people need to use precision sensitive devices, it is important to consider this relationship; this article will deal with this functional relationship.
