| 摘 要： | 阐述了声异常因子、声传播异常的概念．讨论了声传播异常在研究不均匀介质中的传播损失、混响及水声设备作用距离等方面的应用．仿真与实验证明，声传播异常是表征不均匀介质中声传播条件的有效手段，利用声传播异常进行传播损失、混响计算，或者利用声传播异常改进声呐方程进行水声设备作用距离的预报均具有较高的准确性。是一种行之有效的方法．

| Abstract: | The sound abnormity factor and sound transmitter abnormity are described in the paper. The application of sound transmitter abnormity in studying the transmitter loss, reverberation and acoustic equipment acting distance is discussed. The computer simulation and lab experiment testify that it is a valid means by use of sound transmitter abnormity to describe sound transmitter condition in asymmetric medium. Also it is a valid means by use of sound transmitter abnormity to compute transmitter loss and reverberation. |
