摘　　要：设计了一种新型的单基三电极石英晶体谐振器,并在大气环境条件,测试了在单独激励和同时激励状态下镀金电极、镀铝电极对应的石英晶体谐振器的谐振频率及频率稳定性,比较了不同激励电路对相同谐振器频率稳定性的影响。根据实验结果,分析了电极材料和激励电路对石英晶体谐振器谐振频率及频率稳定性产生影响的原因,提出了改进措施。为改善石英晶体谐振器谐振频率特性,进一步提高石英晶体谐振器谐振频率稳定性提供了依据。This paper designed a new-style of same-base tri-electrode quartz-crystal resonator, and tested the resonator fre- quency and frequency stability of this resonator plating anrum and aluminum under the conditions of atmospheric circulation, when motivated by one circuit or more at the same time. It compared the influence of frequency stability of the same resonator motivated by different circuit. Based on the experimental result, this paper analyzed the cause which influenced by plating different electrode stuff and different motivated circuit. It provided some foundation of improving the resonance frequency characteristic, and improving the frequency stability of the quartz crystal resonator.
