Abstract :
A reliable quadric formula for frequency turn-over temperature vs. electrode film thickness in the quartz crystal tuning fork is proposed and the coefficients are experimentally determined by the least squares method. Reliable experiments with respect to frequency temperature characteristics for quartz crystal tuning forks are carried out. In particular, a new analysis for the Young´s modulus of the electrode film is also described, and it is expected to be valuable to film technology
