polyvinylidene difluoride meaning in English

聚偏氟乙烯

In the areas of impact dynamics and high velocity impact dynamics , measuring impact load and pressure between two contacted interfaces is still a difficult work . polyvinylidene difluoride ( pvdf ) piezofilms are of interest to solve the above problem as potential gauge materials since they have quick response to dynamic load and available plasticity
在碰撞及高速碰撞动力学的研究中，界面与界面之间压力、撞击载荷随时间的变化等的测试一直是一个难题， pvdf压电特性的发现为解决这一难题提供了可能。
