一、序言随着科学技术,特别是电子技术的飞速发展,压电石英谐振器(简称晶体)和晶体滤波器在无线电通讯、导航、载波电话、电视广播、深空跟踪、测量仪器、电力传输、手表工业等方面都获得了广泛的应用。由于通讯信道增多,频率密集,频率和时间计量精度要求越来越高,所以对压电石英谐振器频率精确度,稳定度提出了越来越高的要求,石英谐振器的频率也越来越高。为了更好地检测、分类、正确使用,同时促进石英谐振器及器件的
First, the preface With the rapid development of science and technology, especially the electronic technology, piezoelectric quartz resonator (crystal) and crystal filters in radio communications, navigation, carrier phone, television broadcasting, deep space tracking, measuring instruments, power transmission , Watch industry, etc. have been widely used. Due to the increase of communication channels, the frequent frequency and the higher accuracy of frequency and time measurement, higher and higher requirements are placed on the frequency accuracy and stability of piezoelectric quartz resonators. The frequency of quartz resonators is also increasing high. In order to better detect, classify, and correct use, while promoting quartz resonators and devices
