摘　　要：针对深海会聚区特征参数计算的问题,分析了深海会聚区现象的形成机理,建立了会聚区距离计算模型,通过对某海区会聚区距离的统计分析,得到了会聚区距离与表面声速、临界深度之间的对应关系,实现了会聚区距离的快速预报。该方法物理意义明确、结果简单、便于应用,较好地反映会聚区距离与环境参数的关系。Aiming at the problem of convergence zone characteristic parameter computation in deep ocean, the mechanism of convergence zone in deep ocean was analyzed and a convergence zone space computation model was established. Through statistical analysis of convergence zone range in certain sea, the relation of convergence zone space and surface velocity of sound and critical depth was obtained, realizing the quickly prediction of the convergence zone range. This method has the characteristic of physical meaning definitude, simple computation and easy to application, which preferably reflect the relation between convergence zone range and environmental parameters.
