摘　　要：采用独立常数法对盐度分层环境中水面舰船尾流电导率场进行半经验分析 ,获得了舰船尾流横截面的扩展和衰减规律以及尾流横截面上的电导率信号的分布规律 ,可为鱼雷的电导率探头追踪水面舰船尾流的数学模型提供基础 .The semi\|empirical analysis is conducted for the conductivity field in the wake of a surface ship in a salinity\|stratified fluid in terms of Independent Constant Method. The laws for the expansion, the decay and the distributions of the conductivity signal in a cross section of the wake are obtained, which may provide the basis for the mathematical model for conductivity probes of a torpedo to trace the wake of a surface ship.
