中文摘要 | 作為一個共振器,基本頻率與次高頻之差要越大越好。這個差決定於振 動模式及材料性質。摻雜之Pb1+x(Zrλ,T1-λ)O��+x(簡稱為PZT)之陶瓷共振器 之Zr,bT:配比和其形狀是本研究之主題。圓形及方形共振器之頻率差與PZT之 相有關:正方桂及斜六面相之差比較大,而兩相混合者較少。這是因為兩相之彈 性係數不同之緣故。 |
英文摘要 | As a resonator, the separation between first overtone and fundamental frequencies and frequency constant are expected as large as possible. This separation is dependent on the vibrational modes of resonator, and properties of materials. Doped Pb1+x(Zrλ, Ti1-λ)O��+x X=0.03 (designated as PZT) ceramic resonators with different Zr/Ti ratios and sample geometries were conducted in this research. The separation for circular and square resonators was foundlarger for PZT with a tetragonal or rhombohedral phase as compared to that with coexistence of both phases. This behavior is due to the difference in elastic compliances for PZTs with different crystal structures. |
