摘　　要：温跃层对声纳探测有着重要的影响。总结近海温跃层的分布特征和变化规律,研究恒定声速、恒定温度、温跃层、冷中间层和暖中间层情况下的声线传播和声纳盲区的特征。The thermocline is important to the sonar detection. The distribution characteristics and change regulations of thermocline in sea are summarized. The features of sound line spreading and sonar blind area in a lot of circumstances, such as fixed sound velocity, fixed temperature, positive and negative thermocline, warm and cold middle layer, are studied.

关 键 词：温跃层 声纳探测 盲区 评估
