压电高分子 meaning in English

piezoelectric polymer

Also , for material showing pyroelectric properties , electric charges will appear under the effect of temperature . according to these proprieties , a piezoelectric element is an electromechanical transducer ( energy converter ) . at present , most of the piezoelectric material is film or ceramic cylinder
聚偏氟乙烯( pvdf )作为一种压电材料，具有很强的压电效应和热释电效应，也是目前在压电高分子材料中研究的较为系统、应用最广泛的高聚物。
As a new kind of piezoelectricity macromolecule material , pvdf ( polyvinylidene fluoride ) has not only lower density , but also better piezoelectricity , good mechanical performance and plasticity . when a particular shaped pvdf film is used as an error sensor and is bonded to the surface of the measured structure , there will be little effect on the system
由于pvdf ( polyvinylidenefluoride聚偏氟乙烯)是一种新型的压电高分子材料，它不仅密度低，而且具有较强的压电性，机械性、可塑性好等特点。用特定形状的pvdf薄膜作为误差传感器，将它贴在结构体表面上时，对系统产生很小的影响。
