中文摘要:
      本文从波动方程出发,对楔形变幅器的频率方程作了理论推导,将本文所述的变幅器参数代入该方程,用计算机求得这种不锈钢楔形变幅器的辐射面每磨去0.01mm,其共振频率将上升约2Hz,理论值和实验值基本吻合。
英文摘要:
      Based on the wave equation, the frequency formula of the wedged amplitude transformer is studied in this paper. Substituting the known parameters of the amplitude transformer into the formula, the stainless steel amplitude transformer’s resonance frequency will go up 2Hz when its radiation surface is ground off 0.01mm. The theoretical values agree with experimental results probably.
