The surface acoustic waves stress sensitive properties of piezoelectric crystal la3ga5sio14 base on stress sensitive coefficients 基于应力敏感系数的硅酸镓镧晶体声表面波应力敏感特性
The travel time of lcr wave and applied stress showed well linear relationship in the qualitative and quantitative experiments , experimental result matched with the theory , achieved the anticipative requirements . these experiments validated the feasibility of evaluating the stress with lcr wave based on tdc travel time measurement preliminarily 定性实验与定量实验显示, lcr波传播声时与加载应力具有良好的线性关系,实验结果与理论基本相符,达到了预定要求,也初步验证了基于tdc声时测量的lcr波应力检测方法的可行性。
