There are some parameters that influence the multilayer microperfrated structure, which makeacoustic impedanceand absorption cofficient to compute complicatedly.摘要影响双层微穿孔结构的参数很多，其声阻抗及吸声系数的计算复杂。 In addition, when some noise is artificially added to the multilayer model, the function of the smooth processing is examined to control the variation of acoustic impedance.
对复杂的间断声阻抗模型，人为地附加了较强噪音，以考察“平滑处理”控制声阻抗变差的作用。 cnki
Up till now, there is no accurate standard for the optimum acoustic impedance of the coupling medium.
目前国内超声医学界对最佳耦合剂声阻数值的选择尚无较为准确的说法。 cnki |
