piezodielectric meaning in English
压介质
Examples
- Smart materials and structure have definite requirements of sensor components and driving components , for example , they can adhere well to the matrix and have higher strength , fatigue strength , more broad scope of frequency response and faster response speed , etc . piezodielectric ceramics have characteristic of easily preparing , heat - resistance , wet - resistance , high strength and broad scope of frequency response , etc . furthermore , it has piezoelectric effect and inverse piezoelectric effect , namely it can produce electric potential energy when it is transformed by mechanical strength and its mechanical dimension can be transformed when voltage is put on it
压电陶瓷能与基体材料很好结合,具有制备容易、耐热、耐湿、强度高、频响宽等特点,另外它具有正压电效应和逆压电效应,即当它受到机械力变形时,能产生电势,对它施加电压时,能改变其机械尺寸,因此它在智能材料结构中既能用作传感元件又能用作驱动元件。 - Multiple activation is that several piezodielectric ceramics are used as excitation sources , the neighboring piezoelectric discs used as sensors to record the propagating waves , and one piezodielectric ceramic act as both excitation source and response source , which can be used alternatively to form multipoint excitations and multipoint responses
多激励是指用多个压电陶瓷做为激励源,而且每一个压电陶瓷都可以同时作为激励和响应,可以轮换使用,因此是多点激励,多点响应。
