piezodielectric 中文意思是什麼
piezodielectric
解釋
壓介質-
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
壓電陶瓷能與基體材料很好結合，具有制備容易、耐熱、耐濕、強度高、頻響寬等特點，另外它具有正壓電效應和逆壓電效應，即當它受到機械力變形時，能產生電勢，對它施加電壓時，能改變其機械尺寸，因此它在智能材料結構中既能用作傳感元件又能用作驅動元件。 -
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
多激勵是指用多個壓電陶瓷做為激勵源，而且每一個壓電陶瓷都可以同時作為激勵和響應，可以輪換使用，因此是多點激勵，多點響應。
