【摘要】 本文从平衡原理出发,分析了手表用音叉型石英谐振器两臂不平衡时对其等效电阻的影响。利用音叉简化的自由振动模型,导出了其等效电阻是不平衡量的二次函数,并由实验验证其结论是正确的。本文所用的实验方法也为光刻腐蚀音叉的平衡和调频提供了有效方法。更多还原

【Abstract】 Based on balance principle,the influences of unbalance of two a（?）ms of quartz tuning fork resonator on its equivalent resistance R₁ have been analyzed.The equivalent resistance is a square function of the unbalantity.This relationis derived out by using the simlified free vibration model of tuning.Theexperi-ment method proposed here can be used for efficiently balancing and adjustingthe tuning fork manufactured by photolithography.更多还原
