  质海底的负声速梯度浅海中简正波的衰减系数
• The sound speed profile is another important factor , the bigger sound speed gradient , the faster reverberation intensity decay and the other factor to the reverberation intensity decaying is sea floor inclination , the greater the slope angle , the slower reverberation intensity decav
  其次，对混响强度影响的第二大因素是声速梯度，声速梯度越大，混响强度衰减越快。第三，海底倾斜角也会影响海洋混响的衰减，海底倾斜角越大，混响平均强度衰减越慢。
• Lt is obvious that the decaying rule of average reverberation intensity is affected by scattering coefficient of sea floor , sound speed profile , inclination of bottom etc . the sea floor scattering function is the most importan factor to the intensity decaying rule
  结果表明：海底散射方向性指数因子、海水声速梯度、海底倾斜角等对海洋混响平均强度的衰减皆有影响。海底散射方向性指数因子对其影响最大，即适当选取海底散射模型是浅海近程混响建模的首要因素。
