查询词典 compressive

The results show that:(1)the low-noise source-follower circuit can be effectively used to measure the output of PVDF thin film;(2)the piezoelectric coefficient D33 of the PVDF is very sensitive on temperatures;(3)the value of D33 intensively fluctuate in initial loading stage,this means that a pre-load is needed in practice application to keep a constant piezoelectric coefficient D33 of the PVDF;(4)when the compressive load is imposed on the surface of the PVDF along a incline direction,D33 value is obvious changed with changing incline angle,and(5)the frequency bandwidth of the PVDF thin film is very wide,it is more suitable to measure strike or impact loading at various loading conditions.

结果表明：(1)低噪声源跟随电路可有效测量PVDF 薄膜输出；(2)PVDF压电薄膜的压电系数D33对温度很敏感；(3)D33值在加载初始阶段波动很大，所以实际应用中应给PVDF提供一个预压载荷，以确保有一恒定的压电系数D33；(4)当压载荷沿倾斜方向作用在PVDF 表面时，由于有剪切力作用，D33 值会随着倾斜角的变化发生显著改变；(5)PVDF 薄膜具有很宽的频响，更适用于测定不同载荷条件下的侵彻或冲击等动态载荷。
