Finally, we conclude that the addition of the matching layers results in the widening of the transmission frequency for the piezoelectric transducer. 本論文成功地藉由傳輸矩陣法模擬出壓電換能器多層匹配層結構的理論架構及數值計算。
The PZT matching layer redistributes the frequency spectrum of an original broadband ultrasonic probe, and acts as a frequency filter without reducing the wave amplitude. 此層鋯鈦酸鉛匹配層可將原本超音波探頭之寬頻率分布過(guò)濾成某些特定頻率之峰值，且沒(méi)有降低該頻率峰值相對于原始探頭強度之強度。
