摘　　要：海洋环境要素的阶跃变化会引起跃层,跃层现象对水下载体的活动有较大影响.为便于水下活动,载体根据环境要素的跃层变化随时调整行动方案,该文通过插值算法得到跃层分析的基础数据——温度、盐度和密度等海洋环境要素的统计数据,探讨了跃层分析算法的选择问题,重点研究了有效利用实时传感器数据分析跃层状况的方法,然后依据跃层的示性特征绘制等值线图,进而分析出该区域主要在跃层的变化状况和特点,为指导水下活动载体航行、保证航行安全提供信息支持.The step changes of oceanic environmental factors may generate thermoclines in the ocean, which will dramatically affect the movements of underwater vehicles. In order for underwater vehicles to modify action plans according to the changes of thermoclines at any time, we got the statistic data about oceanic environment such as temperature, salinity and density by interpolation algorithm. The problem how to choose thermocline analysis algorithms was discussed. The emphasis lies in the analysis of thermocline status with real time measured data from various sensors. Then the isolines were plotted according to the characteristics of thermoclines, so that we can get the changes of thermoclines, providing information supports for the navigation and security of underwater vehicles.
