【摘要】 在超声传播参数的测量中,衍射效应会给测量带来假象。本文讨论了衰减及非线性声参量B/A测量中的衍射修正问题。证明加入此修正后的测得值更加真实可靠。更多还原

【Abstract】 Diffraction effect will cause artifact in the measurement of acoustic propagation parameter. We discussed the diffraction correction incorporated in the measurement of acoustic attenuation and nonlinearity paramnter. It is shown that the results after correction are more convincing.更多还原
