acoustic impedance density的用法和样例:

例句

  1. When a wave emanating from the surface reaches a boundary between two media that have different acoustic impedance (the product of density and velocity), some of the energy is reflected back into the upper medium.
    当一个从地面激发的波动到达具有不同声波组抗(速度与密度之乘积)的两种介质之间的分间面时,其部分能量将被反射并回到上覆介质中。
  2. Negative coefficients occur where there is a decrease in acoustic impedance across the reflecting interface.
    当反射界面上下两侧的声波组抗降低时,反射系数就会出现负值。
  3. Methods To check on objective acoustic impedance and subjective pure tone audiometry.
    方法对外伤性聋进行客观声导抗测试和主观纯音测试。
  4. And the fluid micro-annulus does not affect the shape of spectra, but its existence is equivalent to lowering the acoustic impedance of the cement.
    水泥胶结类型不同,反射谱的特征亦不同;微环的存在相当于水泥环声阻抗变小,基本不影响反射谱的形态。
  5. Opposition to the flow of sound through a surface,acoustic resistance is the real component of acoustic impedance and acoustic reactance is the imaginary component.
    声音在通过一个表面时受到的阻力,声阻是声阻抗的实部,声抗是声阻抗的虚部。
